Car Key Fob Replacement

Many vehicles use key fobs to lock and unlock doors and allow you to start your vehicle. Typically, replacing a standard fob requires a visit to the dealership, which charges according to the vehicle's make.

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

Battery

If your key fob isn't working, the first thing you should do is replace its battery. These little devices that have taken the place of traditional keys have more in them than just buttons that lock and unlock your vehicle. Depending on the frequency at which you press them, they are constantly emitting a coded signal in a unique sequence that is sent to the car's receiver to either lock or unlock it. Fobs aren't impervious to damage, however as with any other piece of consumer technology that spends most of its life jostling around in your pockets and purse they may cease to function as they age.

If you're lucky, your new car dealer will sell batteries for keys compatible with your car. If they don't, you can find them at a variety of auto parts stores and even at big-box retailers. G28 'll typically need a CR2032 button cell battery that can cost between $2 and $4 American for a pack of two. To avoid damaging the electronic circuit board, you'll have to carefully remove the old battery from your key fob before replacing it with a new one.

Some of the newer fobs include a tiny key that can be pulled out in the event that your keys aren't working to open the door or start the car. This is a convenient feature, but it can be risky for those who are prone to losing their keys. Some people utilize a wireless remote locking system that is based upon an RFID chip embedded in the key fob. If you're experiencing issues with your car, contact the manufacturer and ask if the chip might be reset. You can also contact a locksmith.

You could be able to complete the programming yourself if it is possible to purchase a replacement fob at an amount you are comfortable with. This is usually a cheaper alternative than buying an alternative key at the dealership. Be aware that not all replacement keys from the aftermarket will work with your car and require specialized equipment for programming.

Programming





Modern cars are usually equipped with electronic key fobs that allow you to unlock and start the vehicle remotely. You may be able to create a new key if you lose yours, or if you need one. Instructions are typically available on the internet. The exact procedure will depend on the model of your vehicle. Some owner's manuals also contain details on programming. Make sure that your key fob is powered by a new battery before you attempt to reprogram it. They are affordable and easy to replace, however an exhausted battery can interfere with the process. Close all doors at once. One open door could affect the functioning of the fob.

To reprogram a key fob, turn off your vehicle and take the original key from the ignition. Press the lock button on the new fob within a predetermined time frame, usually about 10-30 seconds. The car could respond by turning on the lights, turning off the locks or emitting an audible chime to signal confirmation that the fob is programmed. Repeat this procedure for any additional fobs you want to add to your car's system.

Be aware that this reprogramming technique is only available for vehicles that utilize the same technology. If your car has an alternative type of key fob, or has an additional ignition key made of metal it will require specialized programming that can only be performed by an authorized dealer.

A lot of dealerships offer this service for a flat price however, you may be better off contacting an automotive locksmith instead. They have the tools to complete the task for a fraction what you would spend at a dealership. They might even be able to travel to your home to complete the work.

If you decide to go with the dealership, ask them what they charge and whether they have an assurance on the work. Also check your new-car warranty and auto club membership as well as your car-insurance policy to see whether it covers any malfunctions or lost fobs that are related to them. If you're in good standing with your mechanic, they might even inform you of their pricing for this service prior to scheduling an appointment.

Dealerships

You might be enticed, in the event that you lose your keys, to visit a dealership to get them replaced. But dealerships often charge more than other places for this service, and may not be the most affordable price. Hardware stores and locksmiths are two other options to replace your key fob. These stores are usually less expensive than dealerships, and can save you money.

A car key fob allows you to open and start your car without traditional keys made of metal. It's usually an oval or rectangular piece of plastic that has buttons that let you lock and unlock your vehicle or set off an alarm or open the trunk. Fobs were first popular in the late 90s, and many vehicles include them as standard features. They're a convenient method of opening your vehicle, but they could also make it easier for thieves to steal your car.

The most commonly used car key fob is the push button starter. It is connected to the ignition of your car. You can typically find these at the dealership or an auto parts store. Other kinds of car keys fobs include switchesblade keys, which contain the key made of metal inside a plastic cylinder, and keyless entry fobs. They are popular because they let you unlock and start your vehicle without a physical key.

Many dealerships inflate the cost of key fobs as they know that consumers will be willing to pay for any service in order to return their vehicle. It can be difficult to find a replacement fob for a reasonable price. However, you can save some money by using the correct battery and programming it in a different way.

Whether you have a traditional metal key, a push-button starter or one of the latest smart keys, you can get a replacement for it at a locksmith that's not associated with any particular car manufacturer. There are many locksmiths that carry a large selection of replacement keys, and they can cut and program them for less than the dealers. You can even make use of a search engine in order to locate an independent locksmith in your area.

Locksmiths

If your key fob has been lost, you will need to find an expert to replace it. But it may not be as costly as you think, especially in the event that the key fob comes with a smart feature like automatic locking or remote start button.

Smart keys are found in the majority of modern vehicles to stop theft. They work by sending a unique security code every when the key is used. These codes aren't saved on the fob, but in an embedded chip that communicates with the car to unlock doors and also start the engine. Because of this extra layer of security, it's usually only certified locksmiths or car dealership technicians who have the equipment and know-how to reprogram replacements for these types of keys.

You may be able to purchase a new keyfob at a locksmith or hardware store that specializes in security for cars at a lower cost than you would pay if you went through the dealer. You'll still require a professional to program your fob. This may require the same equipment as the dealership.

Certain automakers provide instructions for self-programming fobs in their owners' manuals or on the internet. These steps can be tricky and you may need another key fob to complete the procedure. It's wise for both owners and tenants to have two key fobs that work before they lose one.

If your car has traditional metal keys you can purchase one at a key cutting or hardware store, provided that the metal key wasn't lost in the fob. Fobs with a transponder element on both the key shank and the fob are likely to need to be professionally programmed, however, which can add up if you need to have more than one spare or the key needs to be replaced.

People who own German automobiles, for instance, that have a "flip" function which is akin to a switchblade knife, could only get replacement fobs from the dealer. The reason for this is that these fobs typically use a special type of transponder that can only be reset and programmed by the dealer's service department, which is typically the only manufacturer with the necessary equipment to do so.
