Anatomy of the SansKey Keyless Start System

The PBS-100 is flexible enough to be installed in any vehicle. Installation is easy with advanced setup features and a single Learn Button. Plus, non-intrusive installation means that vehicle wiring can stay intact.

Best of all, every feature is optional and the Brake, Door and Enable inputs can either be ground or voltage switched. Meaning you won't have to wire up extra relays just to get the inputs to work.


    • To use a single button or toggle switch and button.
    • The ACC circuit can be turned on when Disabled or not.
    • The Retained Accessory Power feature is used or not.
    • The Auto-Crank feature is used or not.
    • To use the Run LED dim feature or not.

Adjustable Settings:

    • Auto-Crank max crank time. Adjustable from 0s to 16s.
    • The push button's LED is dimmable for nighttime driving.

Other Functions:

    • The brake must be pressed to start and shut down vehicle. Alternative, emergency shutdown methods are to hold the start button for one second or press the start button 3 times in quick succession.
    • Enable relay is activated when the PBS-100 is enabled, allowing additional control and integration to other systems.
    • Enable LED output is activated when the PBS-100 is enabled.
    • ACC LED output is activated when the ACC circuit is activated.
    • Run LED output is activated when the vehicle is started.

Mounting the Module

There are two mounting tabs, one on each side, of the module. Each tab has a single 0.197"(5mm) diameter hole. The module is not weatherproof and must be mounted within the vehicle's cabin, away from objects or people in order to avoid damage.

Module Dimensions

    5.125"L x 2.375"W x 1.125"H

5 Position Receptacle
There is a latching mechanism to prevent the harness from accidentally being pulled out.

Jumper Block
The jumpers are used to tell the module if an input is voltage-switched or ground-switched.

6 Position Receptacle
There is a latching mechanism to prevent the harness from accidentally being pulled out.

8 Position Receptacle
This harness has bigger wires to handle more current. There is a latching mechanism to prevent the harness from accidentally being pulled out.

LED-Dim Potentiometer
This potentiometer is used to set the dimmed level of the Run LED for the LED Dim Feature

DIP Switches
These switches are used to activate the different features of the PBS-100.

Auto-Crank Potentiometer
To prevent excessive cranking, the Auto-Crank feature will stop cranking after a set period of time. This potentiometer sets that time.

2 Position Receptacle
This receptacle is not used. It is included in order to integrate with future SansKey products.

Learn Button
When pressed, this button records the settings of the module and stores those settings in memory.

The Auto-Crank feature allows you to start the vehicle with a tap of the start button. When using Auto-Crank, there is no need to hold the button to crank the starter motor. Press and release the button and the PBS-100 will do the rest. When Auto-Crank is used, the PBS-100 will sense when the RPMs have reached the previously learned idle RPM value and will then stop the starter motor from cranking the engine.

Once the vehicle is turned off, the Retained Accessory Power feature gives you the option to keep the Radio (and anything else powered by the ACC circuit) powered until the door is opened. The ACC circuit will stay on for up to 10 minutes before turning off to conserve battery power.

The LED Dim feature provides a convenient way to dim the start button's LED at night. During the day, the LED looks cool. At night, the brightness can be distracting and cause glare. The solution is to dim the LED when the vehicle's headlights are turned on.

To ensure that the vehicle can only be started by an authorized person, the PBS-100 can be enabled and disabled. The Enable Input should be connected to a switch, relay, security system or other mechanism that can be used to determine when the PBS-100 should be enabled or disabled. Both a momentary and toggle setup will work.

Whether you want the ease of using a single button or the style of using a toggle switch and a button, the PBS-100 has got you covered. The method you choose is chosen with the simple flip of a DIP switch.

There are two possible modes of operation when using a single button setup.

The first, default mode is mainly useful for vehicles with automatic transmissions. While the vehicle is in park, press and hold the Start Button. After 0.5 seconds, cranking will begin. If the Start Button is pressed and released before 0.5 seconds elapses, then only the ACC circuit will power on.

The second, alternate way works as follows: If the brake input is pressed when the Start Button is pressed, the engine will begin to crank. If the brake input is not pressed when the Start Button is pressed, then the vehicle will not crank and only the ACC circuit will turn on.

Three quick taps of the Start Button, or a press-and-hold of the Start Button lasting one second will immediately cut power to all outputs. This is a safety feature to allow the driver to cut power even while the vehicle is in motion. Having this feature could be invaluable if your vehicle ever starts to accelerate uncontrollably or will not stop.

There is a single Learn Button that is used to record and implement all settings; making setup that much easier.

During setup, the PBS-100 automatically knows whether the brake, door and enable switches are normally on or normally off; eliminating extra steps to make installation easier and faster.

There are three LED outputs that can be used to indicate the system’s status. You could hook up individual LED's, wire up relays to control something else, or use a button with three LED's to easily see the system's status.

An adjustable potentiometer is used to set the maximum time the PBS-100 will crank without the vehicle starting. This is a valuable feature to keep from draining the battery when the vehicle has a hard time starting. The max crank time is adjustable from 0s-16s. Alternatively, cranking can be stopped at any time by pressing the Start Button a second time after cranking has begun.
