Car Key Fob Replacement
Many cars use key fobs that allow you to lock and unlock the doors and begin your car. Replacing a standard key fob usually requires an appointment with the dealer who will charge based on the make of your vehicle.
Consumer Reports has some simple ways to save money. Here's how:
Battery
The first step to take in the event that your key fob is not working is to change its battery. These tiny devices that have taken over the place of traditional keys have a lot more to offer than just buttons that unlock and lock your car. Depending on how often you press them, they are constantly sending out an encoded signal in a unique sequence that goes to an inside car receiver to either lock or unlock it. Fobs may 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 dealer will sell replacement keys fob batteries that are compatible with your vehicle. If not, they're available at auto parts stores or big-box retailers. You'll usually want a CR2032 button cell battery, that can cost between $2 and $4 American for a set of two. You'll need to take the old battery 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 of the newer fobs come with a small key that can be pulled out if your keys don't work to open the door or start the car. While this is a great feature, it could be a risk for people who have the tendency to lose keys. Some people utilize a wireless remote locking system that relies on an RFID chip embedded into the key fob. If you have trouble with this, you'll need to contact the manufacturer of your car to determine if the chip can be reset or an locksmith if you need.
If you're able to purchase a replacement key fob at an amount you're comfortable with, you may be able to program it yourself. This is typically a cheaper option than purchasing a brand new key from the dealer. But, be aware that not all key fobs from aftermarket will work with your car, and that most require specialized equipment to program.
Programming
Modern cars come with electronic key fobs which allow you to start and unlock your car remotely. If you lose yours or need a new one, you might be in a position to program a replacement yourself. Instructions are typically available on the internet. The exact procedure will depend on the model of your car. Some owner's manuals also contain detailed programming information. Before you try reprogramming your key fob, ensure that you have new batteries. These are cheap and easy to replace, but an over-charged battery could interfere with the process. It is also a good idea to close all doors, since even one door that is left open could impact how well the fob works.
To reprogram a remote, switch off your car and take out the ignition key that was originally used. Press the lock button on the new fob within the specified time frame, usually about 10-30 seconds. The car could respond by cycling the locks, switching on the lights, or emitting a chime signal to confirm that the fob has been programmed. Repeat this procedure for any additional fobs you wish to add to the system.
This reprogramming method is only applicable only on vehicles that have the same technology. If your vehicle has different types of key fob, or has a separate metal ignition key It will require special programming that must be performed by an authorized dealer.

If you have a good relationship with your mechanic, they might even let you know their pricing for this service before you schedule an appointment.
Dealerships

Locksmiths
If your key fob is missing, you'll most likely have to hire a professional to replace it. But that might not be as costly as you think, especially if the key fob includes an advanced feature, such as the automatic locking feature or remote start buttons.
The majority of modern vehicles have smart keys designed to guard against theft by sending unique security codes every when a button is press. These codes aren't stored on the fob, but instead in an embedded chip that communicates with the car to unlock doors and start the engine. Because of this extra layer of security, it's usually only locksmiths who are licensed or dealership technicians who have the equipment and know-how to reprogram replacements for these types of keys.
Based on the model of your car and year, you may have the option to buy a new key fob at an auto repair shop or a locksmith that is specialized in automotive locksmithing for less than what it would cost through the dealer. You'll still have to hire an expert to program your fob. This could require the same equipment that the dealership uses.
Certain automakers offer instructions for self-programming fobs in their owners' guides or online. These steps can be tricky and you may need a second key fob to complete the process. For that reason, it's prudent for owners and lessees alike to have two functional key fobs prior to experiencing the frustration of losing one.
If your car has a traditional key shank in addition to a smart key, you'll be able to purchase a spare key at a hardware or key cutting store for relatively inexpensive in the event that the metal key isn't lost together with the fob. Fobs with transponders on both the key shank as well as the fob may need to be programmed by a professional, however this can be expensive when you need to create more than one spare or if the key requires replacement.
People who own German automobiles, for instance, that have the "flip" function, which is akin to a switchblade knife, might only be able to find replacement fobs at the dealer. This is because these fobs operate on a transponder which can only be reset or reprogrammed at the service department of the dealer.
