A lot has changed in the automotive industry as a result of new technologies introduced. Instead of the AM/FM radios of old, cars come equipped with infotainment centers and Bluetooth phone connections. Backup cameras allow the driver to view what is behind them without having to turn completely around in their seats. Automatic braking systems automatically sense an impending collision and automatically apply the brakes. Even the way we open and lock our cars has given way to technology with the advent of keyless entry Fobs.

Keyless entry is a newer method of opening and locking your car without using a traditional key. It is more convenient than using a metal key because you can unlock and lock all of the car doors with just the push of a button. You don’t have to go and open each individual door to let the other people enter or exit the car anymore.

​The remote is programmed to work with one specific vehicle, and the vehicle will usually come from the factory with a couple of remotes that have already been programmed for your use.

How does it work?

A keyless entry remote is essentially a short-range radio transmitter. In order for it to work properly it needs to be within a reasonably close distance to the car. When you push down the button on the remote, an electronically coded signal is sent to the receiving device inside the car to locks or unlock the car doors.

How can you replace a Keyless entry FOB if you lose it?

Replacing a keyless entry FOB will largely depend on the make and model of the car you drive. These FOBS contain a transponder chip that electronically communicates with the vehicle’s navigation system that has to be near the car in order for it to work. Each vehicle has its own specific procedure to program a new FOB remote. As such only a licensed automotive locksmith or the dealership of the make of your car can replace and program the transponder chip.

So How much will a Replacement Keyless Entry FOB Cost?

As reported in Consumer Reports, if you lose the key and fob, you can expect a dealer replacement and programming to cost $200 or more, depending on the vehicle and the key’s design. A Lexus dealer quoted $374 for a new key, fob, and programming, and a BMW dealer said replacement keyless fobs could be as much as $500, depending on the model.

Can’t I purchase a Keyless Entry FOB online?

You can find key replacement companies online that will sell you a Keyless Entry FOB for less than the dealership in many cases, but you will still have to have it programmed by a dealership or automotive locksmith. The programming is where the bulk of the cost comes into play, so you usually come out ahead if you use an automotive locksmith to replace your Keyless entry FOB.

If your transponder key is damaged or lost, contact your local auto locksmithbefore you go to the dealership, as the dealership will be the most expensive option for replacement.
