Car Key Fob Replacement

Many cars now use key fobs that allow doors to be locked and unlocked and start the car. Typically, replacing a standard fob will require an appointment at the dealership, which charges according to the vehicle's make.

But Consumer Reports reveals some simple ways to save money. Here's how:

Battery

If your key fob isn't working the first thing you need to do is replace its battery. These devices are replacing traditional keys, do much more than unlock and lock the car. Depending on the frequency at which you press them, they are constantly emitting a coded signal in a specific sequence that sends to a receiver inside the car to either lock or unlock it. Fobs can break down over time as does any other piece of consumer electronics that is constantly tossed around in your pockets or purse.

If you're lucky, your new-car dealer will have replacement key fob batteries that work with your vehicle. If not, they're available at auto parts stores, or big-box retailers. You'll want a CR2032 battery usually about $2-4 American per pack of two. You'll need to take the old one from your fob, and then install the new one with care in order to ensure that there is no damage to the electronic circuit board.

Some modern fobs include tiny keys inside them that you can pull out if keys aren't able to open your door or start your engine. While this is a great feature, it can be a risk for people who have the tendency to lose keys. Some use a wireless remote locking system that relies on an RFID chip in the key fob in order to operate the doors. If you're having trouble with this, it's best to contact your car manufacturer to determine whether the chip can be reset, or call an locksmith if you need.

If you're able to purchase a replacement key fob at an affordable price, you may be able to do the programming yourself. This is typically a cheaper option than paying for an additional key from the dealership. But, be aware that not all aftermarket replacement key fobs can be used with your vehicle and require specialized equipment for programming.

Programming

The car may respond by switching on the lights, cycling the locks, or emitting an audible chime to signal an indication that the fob has been programmed. Repeat this process for any additional fobs you wish to add to your vehicle's system.

Be aware that this reprogramming technique is only applicable to cars that use the same technology. If your vehicle has an alternative type of key fob or has a separate metal ignition key it will require specialized programming that must be performed by a dealer.
