Proximity keys are becoming the new norm for modern vehicles.
What exactly is a proximity key?
A proximity key (or smart key) is a small fob that allows keyless entry and ignition when within a reasonable range of your vehicle. Its unique design allows the driver to keep the fob in their pocket when unlocking, locking and starting their vehicle. It certainly makes life easier when you’re juggling bags of shopping!
The smart key is identified via one of several antennae in your car’s bodywork. A radio pulse generator housed within the key communicates via radio waves with your car; the fob can then lock and unlock doors when within an acceptable proximity.
How do you cut a new proximity key?
The transponder chip fitted within the fob can either be cloned or programmed. Cloning is the most common form of transponder duplication; it’s quick and easy, often taking less time than key cutting! We copy the data from the original fob to a new transponder so it is an identical match. Your car assumes it’s the same fob, so both proximity keys are allowed to start the engine.
Programming is when you recode the transponder in a key fob. Typically, a programmer is plugged into your on-board diagnostics interface in order to communicate with your car. Programming data from the computer is used to recode the transponder, so the new fob should function just like the old one.
