Choosing a remote keyless entry system

A basic aftermarket car keyless entry system is an

easy car modification

that will allow you to lock or unlock your driver-side door without inserting a key into the door handle. Fuller systems may include extra features such as remote start capabilities or upgraded security systems.

Check the compatibility: Not all remote keyless entry lock systems will work on all makes and models of cars. Check the product details to make sure the remote system you want is compatible with your specific vehicle.

Pick your options: Some options to consider for remote keyless entry systems include:

Single-door or multi-door unlock

Remote control start

Ability to open the trunk (if applicable)

Connectivity to a smartphone app

Added transmitter range

Car alarm system

Multiple key fobs

Read the reviews: Once you have narrowed down the possible systems for your car and the options you would like, read the reviews and ask around. Specifically, check how difficult the installation process is and whether or not they work in the advertised range.

Use trusted suppliers: You can find keyless entry systems on Amazon, but we recommend that you use trusted auto parts stores like Pep Boys or AutoZone. These establishments may offer additional warranty and return options should the product be defective or not right for your vehicle.
