Gate operator – Access Control

Gate Operator for Sliding Gate, Video & Voice Intercom, Handicap Exit Button

S.A. Locksmith & Security was awarded a project to install a slide gate operator, and intercom system to allow the main office to open the sliding gate remotely. In addition, there was a requirement to add a handicap exit switch plate to allow handicap residents using a wheelchair or motorized scooters to exit the premises, since an exit loop can not not detect a wheelchair.

Also, the front desk needed to have an option to disable the handicap exit button.

Scope of work:

Installation of the following:

  • Gate operator for existing slide gate
  • In-ground exit loop
  • In-ground interrupt loop
  • Audio / Video intercom system at the entrance to the facility.
  • Gooseneck at the entrance for mounting the camera of the intercom system
  • Gooseneck at the exit for mounting the controlled handicap exit switch plate
  • Intercom monitor at the front desk

Products Used

  • Gate operator: Commercial DC Vehicular Slide Gate Operator
  • Brand: LiftMaster Elite Series
  • Model: CSL24UL

Gate Operator & Access Control Components Installation

AC Power to Gate Operator:

The installation included running 110VAC power for the gate operator. An electrician ran the power lines from the building to the location of the operator.

Concrete Pad for Gate Operator:

A concrete slab was needed to secure the operator. The installation manual calls for:

“Attach the operator to the concrete pad with appropriate fasteners. The gate operator should be installed near the front roller of the gate or near the back of the gate (in the open position). The space between the gate and the output sprocket must be a minimum of 4 inches”

Video intercom:

We placed the Video intercom at the entrance of the gate. For that purpose we installed a gooseneck and ran wires from the intercom to the gate operator and to the office. At the front desk at the office we installed the AIPHONE monitor and connected the wiring to the camera of the AIPHONE and the gate operator.

When visitors want to enter the facility, they drive up to the intercom and click the “Talk” button. The front desk personnel can see the visitors, talk to them, and if approved, press a button and open the gate for the visitors. The gate will close automatically after a set delay.

Handicap Exit push-button:

Another requirement was to allow handicap residents with wheelchairs and electric scooters, to open the gate and exit the facility. Therefore, we installed an additional gooseneck at the inside of the  premises and installed a commercial handicap exit button.

When handicap people on a wheelchair or electric scooter wished to exit, they press the handicap exit button and the gate opens. We have also installed a switch at the front desk which allows disabling the handicap exit push-button.

Interrupt Loop:

The interrupt loop is on the outside of the gate.
This loop holds open gate at open limit
The Interrupt loop stops and reverses a closing gate
The Interrupt loop pauses Timer-To-Close at Open limit.

To install the Interrupt Loop we cut into the concrete and placed the loop wire inside. In addition, we sealed the cut with Sikaflex, a special sealant.

Exit Loop:

The interrupt loop is on the inside of the gate.
Opens the gate when a car is above it
Maintains, pauses Timer-to Close at Open Limit
Opens a closing gate and holds open an open gate.

To install the Exit Loop we cut into the concrete and placed the loop wire inside. We then sealed it with Sikaflex, a special sealant.

Safety Devices

The LiftMaster model CSL24UL was designed to work with at least two safety devices:

One for a gate opening and one for a gate closing.
Please note that the opener WILL NOT FUNCTION without these two safety devices installed!
In our installation we used:
IR sensor for gate closing safety: LiftMaster monitored retro-reflective photoelectric sensor Model LMRRUL
Edge sensor for gate opening safety: LiftMaster Monitored wireless edge kit (transmitter and receiver) Model  LMWEKITU

Access Control Downtown San Antonio

Scope Of Work

The scope of work was very different from many other jobs we were asked to perform.

In this case, it was an historic building. The owner wanted to preserve the looks and character of the grounds as much as possible.

All existing gates were manual, our task was to add automatic openers, wireless keypads, and a central access control system.

Usually, when we build and install sliding gate or swing gate, we place exit loops, shadow loops and interrupt (reverse) loops, under the ground. But in this case, the owner didn’t want to dig underground. So, we had to be creative!

The Solution

Virtual loop placed on a short pole

The solution for the vehicular gate loops was to use virtual loops, placed on a short pole above ground.

Since the short poles were placed at the sides of the gates, by some plants and vegetation, they actually blended with the greenery and did not distract much the original view.

Another Challenge

Another challenge we faced was a double pedestrian gate that had to be opened during the day, but had to close and lock automatically at a certain time in the evening. Normally it would be a simple task, but in this case, there was no automatic motor, and the small gates had be opened and closed by hand. So the challenge was how to close and lock an opened gate after hours, when closing it has to be done by hand? The requirement was to have the gate close automatically, without a human intervention.

So again, we had to be very creative and think out of the box!


On the above double pedestrian gates mentioned earlier, we came up with a unique solution:

The first person arriving at the premises opens the small manual double-gates. Once the gate is fully opened, a magnetic latch mounted on the wall will keep it opened. After hours, the access control system which also control that magnetic latch, cuts-off the power to the magnetic latch. Then, the door automatically will close (by means of a special mechanical spring), and will latch into the electric strike plate. In the morning, the electric strike will automatically  dis-engage by the access control system, allowing the gate to be open manually. The gate stays open by the now engaged magnetic lock mounted on the wall.

Recently we did a job at a San Antonio downtown bar "Howl at the moon".
The customer had a Von Duprin vertical rod push bar, 35 series (3527a to be exact) without the rods, so the doors stayed unlocked all the time!
We ordered and installed the surface mount vertical rods for this and it looks great. Please view the photos from this job.

Bentley Key

Bentley Continental 2 doors Sport GT 2007


We are going to program a Bentley key by using the AR32 and the Tango systems.

The EEPROM we are going to program is inside the KESSY module.

As you can see in the photo the Bentley is using a VW KESSY module.

In the two doors Bentley Continental Sport GT the KESSY module is located under the carpet AT the driver side, not far from the pedals; you can feel it with your hand, you will feel a bump underneath the carpet.

To access the KESSY module, you need to remove the 4 bolts which are holding the driver’s seat. There are two bolts in the front and two bolts in the back. You do not remove the seat completely; there are several wire-harnesses connected at the bottom of the seat, so you want to be careful not to damage them. Just move the seat gently so you have enough room to remove the KESSY module from underneath the carpet.

Once you remove the KESSY module, locate the EEPROM. It is a 93C86, 8 pin chip located close to the largest chip, the microprocessor as seen in the following image:


The 93C86can be configured as 8 bit or 16 bit. Checking with an Ohm-Meter for a short between pins 5 and 6 of the chip can tell us how the chip is configured. If there is a short between pins 5 and 6 of the chip it is configured as 8 Bit. In our case, there was a short between pins 5 and 6 so the chip was configured as 8 bit.

Some recommend removing the chip completely from the board.  However, if you short the crystal, you should be able to read and program the chip in-circuit, without removing it from the board. We have confirmed it with the designer of the AR32.

If you are reading and programming the chip in circuit make sure to do the following:

  • Short the Crystal by soldering a wire across the 2 legs of the Crystal
  • Select device 93C86-8Bit from the AR32 library and press INS key (Insert).

If you are reading the device out of circuit select the device 93C86, not the 93C86-8Bit

Make sure all the switches are in the correct positions as shown on the computer display.

Once the file is saved (make sure you add the .bin extension) use the Tango to read the file.

Select the Bentley car from the Tango and load the bin file you read with the AR32.

If the Tango is able to read the bin file it means the file is good. If for any reason the file was not read correctly the Tango will display an error message saying it did not recognized the file.

After the Tango reads the bin file, select a key number (such as 3) place a transponder key inside the Tango slot and press W to write the file into the key (programming it). The Tango creates a new bin file and will ask to save the new bin file with a different name.

Now load the new bin file into the AR32 and write the new bin file back into the EEPROM. Place the KESSY module back in the car and start the car.

Access Control – Case Study


Access Control  Case Study

Project at glance:
Client: Greystar
Location: 2810 Hemphill Park, Austin Texas

S.A. Locksmith & Security in San Antonio Texas was awarded an access control job in Austin Texas. The job was to replace two old tele-entry access control systems which controlled access to elevators, doors, pedestrian and parking garage gates, about 20 in total, and held information of about 500 residents. The two old Access control and tele entry systems were:

1.      Old Linear tele entry and access control units.

2.      Old Sentex tele entry and access control units.

The old systems did not have enough memory to add additional residents to the database. In addition, the individual control panels were not connected to a network, so any deletion or addition of residents had to be done separately, at the location of each control panel, one at a time. There was no communication between the various panels!

In order to reduce cost, the requirements were to use the existing wires and to use the old readers, key fobs and transmitters, as much as possible. The project involved 3 parking garage gates, several pedestrian gates and several tele entry doors and gates.

As we will see, the requirement to use the old wiring was very challenging, since the new systems required more wires than the old system had.

Old Linear Access Control

After evaluating the customer’s needs and the existing wiring, we came to the conclusion that the best solution would be to use the ‘Linear’ systems (now Nortek) and use their more advanced Tele-Entry systems.

We suggested using the AE-2000 plus systems for the tele-entry controllers and the AM-3 plus for the general door and gates controllers. These systems also include transmitters and option to add a remote receiver (the AE2000 plus also has an internal receiver). We used the Transmitters and receivers to control 3 parking garage gates.

AM-CRI Expansion

Altogether we needed to use 10 control panel, 4 of them were Tele-Entry systems. In addition, we needed to use several Linear AM-CRI modules to extend the number of card readers each system can hold and support. We also added an AM-RRR remote radio receiver to the system to control an additional parking garage gate.

The Linear access control system can hold up to 8 panels (units) per network so we ended up using 2 networks: Network A and Network B.

It actually worked well, since the project was divided into two separate groups of buildings, so panels connected to Network A controlled one building complex, and panels connected to network B controlled a second building complex.

To make it convenient for programming the control panels from the offices, we ran wires from network A into an office in one building, and wires from network B into an office in the other building.

Wall Connection Network B


Card Reader - Linear


AM-RRR-Remote Radio Receiver - Linear

Challenges we encountered:

The job became more complicated because of the requirement to use the existing wires of the old installation. Typically, there are many wires connecting the panels to card readers, to elevators, to electric strikes and to magnetic locks.

Because of the large size of the two building complexes, many of the panels were located far away from each other and on different floor levels.

One of the tasks we had to perform was to connect 2 groups of panels to two separate networks. 

In order to establish a network connection between the panels we needed 3 additional wires to connect between all the panels of each group.

This required running additional cables between the units which were located in different places and on different levels of the buildings.

In addition to running extra wiring for the two networks, we also needed to run several extra wires from some card readers to the AM-CRI.

Each Linear AE2000Plus or AM-3Plus supports 4 relays but only 2 readers. In order to add two more readers to each panel, we needed to use the Card Reader Interface box (AM-CRI) which can add 2 more readers.

The problem was that each reader had to have seven wires. In the old system, only 6 wires were connected to each card reader, so we were missing 2 wires for each AM-CRI expansion boxes. As a result, we needed to run additional wires between some card readers and AM-CRI units.

Programming the access control system:

The Linear (now Nortek) software is user friendly, it has great documentation and is very easy to program. All control panels can be programmed from the offices and adding/removing tenants is now a simple task.  

In conclusion: The Linear (now Nortek) access control system was a good choice for this project. S.A. Locksmith & Security was able to use much of the existing wiring of the old Sentex system and complete the job in a timely manner and save money to the client.

Tips to Secure your Home!

The 4 Tips you Must Know to Secure your Home!

S.A. Locksmith and Security (210) 348-3677

Is your home really safe? The 4 tips you must know for a secure home-

Being a locksmith in San Antonio I know there are many things one can do to increase the security of their home, business or car. It’s nice to remember that not every burglar in the world is at Ocean’s Eleven caliber, however any burglar is a threat.

Hiring a locksmith to install new locks or purchasing an alarm system are two ways one could upgrade their security. Aside from
purchasing new equipment one can increase their security without any purchases, exciting huh? Most locksmiths will tell you

security is also in the attitude, not only the fancy products you have. You have to have that motivation to get up and actually do
the work. Here are some easy home tips you can remember to help minimize the chance you become victim to an intruder.


During the night it is more difficult to spot people due to the darkness. Although many burglaries happen in broad daylight, I
have seen first-hand that many “go to work” during the dead of night. A smart locksmith tip is to illuminate the areas around your home. With a lit up property anyone walking on your property can easily be seen by you and your neighbors. This decreases the chance of getting robbed while increasing the chance of your intruder being seen before the damage is done.

Keep tools inside

Often time’s household members will leave tools- screwdrivers, hammers, wrenches, etc. – outside their home, most often by
the garage. Professional locksmiths say that by doing this, you are giving your intruder some useful tools to use to break in. By
remembering to bring in any tools around your property you can vastly limit the success of your intruder.

Hidden keys

This is probably the most occurring problem we hear about as locksmiths. We want to have easy access to our hidden home
key; therefore we keep it very proximate to the front door. Whether it’s under the doormat, above the door frame or inside the flower pot, these burglars know where to look. Think of your hiding spot and then think again. This is basically giving the burglar
the open invite to rob you. Tell yourself you need to hide the key further away from your door, and in a way better hiding spot.

Lighting, hiding tools and HIDING the hidden key are three easy and quick steps you can take today to upgrade your home’s security.
Contact a locksmith in San Antonio for more security tips. San Antonio is a big city, make sure you do all you can do protect your property.

Do you already follow these tips? Have they worked for you? Feel more than welcomed to share any comments or stories with

Parking Safely in Public

Parking Safely in Public

S.A. Locksmith and Security (210) 348-3677

White-van-2-with-sign-2-extractedFor a big city like San Antonio security should always be on your mind when doing anything- and parking is no exception. When leaving your car unattended there are always risks to look out for. This is why parking safely in public is essential.

When parking your car there are several things to keep in mind so you can feel at ease. Typically you want to avoid attention from car thieves at all times. You want to detract anything that highlights your car.

Safe Parking- Illumination

Parking safely in public areas try and find a parking spot that is lit up. Park under a street lamp or next to a lit up building to increase your chances of thwarting a car thief.
The minute a thief sees your car is lit up like the empire state
building he’ll most likely move onto a car parked in darkness.

Safe Parking- Away from exits

When parking in garages or parking lots make an effort to part as far away from the exit/entrance as possible.
Normally a car thief will try to go for a car closest to the exit for the quickest escape. A car parked next to the exit is very attractive to a car thief.
For safe parking make sure to park as far away as you can from the exit. When a thief sees your car he’ll count it as too much work and too high of a risk, and most likely move on.

Safe Parking- Camouflage

Another good tip for parking safely in public is to try parking between a group of cars. A car on its own stands out to a car thief so by parking between a group of cars you can camouflage your vehicle.
A car parked alone will cause a car thief to put his direct attention towards it.
