Keyless Entry System

 Shop Keyless Entry System

With a keyless entry system, you can conveniently unlock and lock your car door with just a push of a button. The key fob, which acts like a radio transmitter, allows you to unlock or lock the door at a distance. Just imagine if you are already inside the house and you suddenly remembered that you haven't locked the car doors yet. By just pressing a button, you can securely lock the doors without having to go outside. Some keyless systems can even allow you to disable the car alarm in seconds. So if you're all set to take advantage of these benefits but don't know how to install a keyless entry system into your car, here's what you need to do:

Tools needed:

  • Wire cutter
  • Electric tape
  • Soldering iron
  • Pliers

Step 1: Familiarize yourself with your car's wiring system. Different car makes and models use a variety of wiring systems. Before you start installing a keyless entry system, make sure you know a thing or two about your own vehicle's wiring system.

Step 2: Remove the dash panels. In order to get access to your car's wiring system, you need to remove the panels located beneath the steering column and dash. Depending on your car's make and model, you may also have to uninstall the side kick panel on the driver's side. Once you've located the wiring harness, use a wire cutter to cut off a few pieces from the black wire covers to have complete access to the wires underneath. Double-check your car's wiring diagram to make sure you're cutting the right black wire cover.

Step 3: Do some wire management. Installing a keyless entry system will require you to remove and re-install plenty of electrical wires. To make you manage the wires easier, look for those that you won't be using and tape them to the main harness using an electrical tape. This way, those unnecessary wires won't get in your way during installation.

Step 4: Link the wires. Strip off a bit of the covering from the wiring harness of your car. Then strip the ends of your keyless entry assembly wires before connecting them to the stripped vehicle wires. Start with the main power, starter, ignition, and parking light wires and then move on to your car's locking system wires. Once the wires are stripped, wrap them around each other to ensure a secure fit. Then solder them together until you get a solid solder joint.

Step 5: Program the different functions. After soldering the wires together and double-checking that the connections are secure, you can now program the various features the system offers. These can include chirp mode, ignition-controlled locks, and door unlock capabilities.

Installation tips

  • When connecting spliced wires during a keyless entry system installation, it's best to use a soldering iron instead of wire tap connectors. This is because wires with solid solder joints last longer than those with connectors that are usually made of plastic.
  • Always have the vehicle manual handy when doing this installation process because identifying the right wires to splice can get tricky.
