Many vehicles use key fobs that lock and unlock doors and start your car. Replacing the standard key fob typically requires a trip to the dealer who will charge according to the model of your car.

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

Battery

The first thing to do if your key fob isn't working is to change the battery. These devices that have replaced traditional keys, do much more than unlock and lock the car. Depending on the frequency you press them, they are constantly sending out a coded signal in a distinct sequence that goes to the car's receiver to either lock or unlock it. Fobs are susceptible to breaking down over time, just like any other electronic device that is constantly tossed around in your pockets or purse.

If you're lucky, your new car dealer will offer replacement key fob batteries that will work with your car. If not, you can find them at many auto parts stores and even at big-box retailers. It is generally recommended to purchase a CR2032 button cell battery, which costs from about $2-4 American for a pack of two. To prevent damaging the electronic circuit board, you'll need to remove the battery that was on your key fob before replacing it with the new one.

Certain newer fobs come with a small physical key stored inside of them that you can pull out in the event that the keys fail to open your door or start the engine. This is a useful feature but can be dangerous for people who frequently lose their keys. Some use a wireless remote locking system that relies on an RFID chip inside the key fob to open the doors. If you are having trouble, contact your car manufacturer and ask if the chip might be reset. You can also contact a locksmith.

If you're able to purchase an extra key fob for an amount you're comfortable with you might be able to do the programming yourself. This is typically a cheaper option than buying a new key from a dealer. Be aware that not all aftermarket key fobs will work with your vehicle and many require specialized equipment to be programmed.

Programming

Repeat this procedure for any additional keys you wish to include in your vehicle's system.

This reprogramming method is only applicable only on vehicles that have the same technology. If your vehicle uses a different type of key fob or an additional ignition key made of metal, it will require specialized programming that must be performed by a dealer.

If your car is equipped with a traditional key shank addition to a smart key that you can get a spare made at a key or hardware cutting store for a relatively low cost and assuming that the original metal key doesn't get lost along with the fob. Fobs with a transponder feature on both the key shank as well as the fob may require a professional to program however, which could increase the cost if you need to have more than one spare or if the key has to be replaced.

Those who have German cars, for instance, that have the "flip" function, which is akin to a switchblade knife could only find fob replacements at the dealer. The reason is that the fobs are typically a specific type of transponder that can only be reset and programmed by the dealer's service department, which is generally the only company with the tools needed to do so.
