Keyless entry systems was designed to eliminate the need of using a traditional key to do a certain action to your vehicle. These modules uses a set of low frequency antennas in the exterior door handles, behind the rear bumper cover and inside the vehicle itself.
In particular, this is used to determine whether the vehicle should be locked, unlocked or be prepared to start if a valid passive key is inside or outside the vehicle.
Keyless entry systems have a very unique feature that changes the signal codes that goes in and out at every successful operation to prevent it from getting copied by hackers and thieves.
Below are the 2 types of Keyless Entry Systems:
?Remote start system
Remote start systems starts the vehicle even without putting the key in the ignition or getting inside of it. It works by simply pressing the start button on the remote.
?Regular keyless entry system
Keyless entry systems operates the locking, unlocking of doors and sometimes the trunk and panic depending on the type of the unit installed.
?Proximity/Smart keyless entry system
Proximity keyless entry systems unlocks the driver door once if remote is near the vehicle or when the door handle is pulled and locking it when the the remotes signal is unreachable or touches the car on exit. This system also operates the trunk, panic and remote start.
Modern vehicles comes with remote start feature but often needs to be activated at the dealership first. Old vehicles that doesnt have these features will need both aftermarket remote start system and alarm systems to be installed. In this case, you will need to use 2 different remotes. One for locking/unlocking the doors, trunk and panic and the other for remote starting the vehicle.
