Car Key Fob Replacement

Many cars are now equipped with key fobs, which allow doors to be locked and unlocked and start the car. Replacing the standard key fob typically requires an appointment with the dealer, who will charge you depending on the make of your vehicle.

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

Battery

The first thing to do when your key fob isn't working is to change its battery. These tiny devices that have taken the place of traditional keys have a lot more going on in them than just buttons that lock and unlock your car. They emit a coded sequence of signals based upon how many times you press them. This signal is sent to a receiver inside the car, and it locks or unlocks it. Fobs are susceptible to breaking in time just like any other electronic device that you carry around in your purse or pockets.

If you're lucky, your new car dealer will have batteries for keys that will work with your vehicle. If not, you can locate them at many auto parts stores and 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. You'll need to remove the old battery from your fob, and then install the new one with care to prevent damage to the electronic circuit board.

Some newer fobs have an electronic key inside of them that you can pull out in the event that keys aren't able to open your door or start your engine. This is a convenient feature, but it can be risky for those who frequently lose their keys. Others use a wireless remote-locking system that relies on an RFID chip in the key fob to open the doors. If you're experiencing issues getting your car manufacturer's attention and ask if the chip might be reset. You can also contact an locksmith.

If you're able to buy an extra key fob for an amount you're comfortable with you might be able to program it yourself. This is typically a cheaper option than buying a new key from a dealer. But, be aware that not all aftermarket replacement key fobs will work with your vehicle and require special equipment to program.

Programming

Modern cars are usually equipped with electronic keys that allow you to unlock and start your car remotely. If you lose yours, or require an upgrade you may be able to program an alternative yourself. The exact procedure will depend on your vehicle model, but instructions are often accessible online. Some owner's manuals also contain specific programming instructions. Before you attempt reprogramming your key fob, be sure it's got fresh batteries. They are inexpensive and simple to replace, but the battery that is exhausted could cause problems with the process. It is recommended to close all doors, since even one door left open can affect how well the fob works.

To reprogram a key fob switch off your car and then remove the original key from its ignition. Press the lock button on the new fob within a set time frame, typically 10 to 30 minutes. The car might respond by cycling the locks or turning on the lights or chiming to confirm the fob is programmed. Repeat this procedure for any additional fobs that you wish to add to the system.

Be aware that this method of reprogramming only works for cars that utilize the same technology. If your vehicle uses a different type of key fob or a separate metal ignition key it will require specialized programming that is only performed by a dealer.

You can save money by using an auto locksmith. Many dealerships charge a flat rate for this service. They typically have the equipment to do the job at a fraction of the cost you'd pay at the dealership. They might even be able to visit you to complete the work.

Ask the dealer how much the service will cost and if they offer the possibility of a guarantee. Check your warranty or auto club membership or insurance policy to determine whether they cover lost fobs. If you have a good working relationship with your mechanic, he or she might even be able to inform you of the cost of this service before you schedule an appointment.

Dealerships

If you've lost your car keys, you might be tempted to go to the dealership to get an alternative. Dealerships might charge more for this service than other places, and they might not be the most affordable option. There are several alternatives for getting your key fob repaired, including hardware stores and locksmiths. These are typically less expensive than the dealership and could save you a significant amount of money.

A car key fob allows you to open and start your car without a traditional metal keys.

Fobs became popular in 1990s and are currently standard on many vehicles. They're a convenient method of opening your car but they can also make it easier for fob thieves to steal it.

The most common type of car key fob is the one with a push-button start, which is affixed to your car's ignition. They are typically located at an auto parts store or dealership. Other kinds of car key fobs include switchblade keys, which house the metal key inside a plastic cylinder and keyless entry fobs.

Smart keys are found in all modern cars to stop theft. They work by sending a unique security code every time a key is pressed. The codes aren't stored on the fob itself, but rather in an embedded chip that communicates with the cheap car keys replacement to unlock doors and even start the engine. Due to this extra layer only locksmiths and dealership technicians have the tools and know-how needed to reprogram these keys.

It is possible to purchase a new keyfob from a locksmith or hardware store that specializes in automotive security for less than what you would have to pay if you bought it through a dealer. But, you'll most likely have to hire an expert to program the fob, which may require the same equipment the dealership utilizes.

Some automakers offer instructions for doing the programming yourself for key fobs on their websites or in their owner's guides. These steps can be difficult and you may require an additional key fob to complete the process. It's sensible for owners and lessees alike to have two functional key fobs before they experience the anxiety of losing one.

If your car also has a traditional metal key, you can get a spare at an hardware or key cutting store, as long as the key was not lost with the fob. Fobs with a transponder on both the key shank and the fob could need to be programmed by a professional, but this can be expensive if you want to make more than one spare, or if the key requires replacing.

Those who have German cars, for example those that come with the "flip" function which is akin to a switchblade knife may only be able to find fob replacements at the dealer. The reason is that these fobs typically use a specific type of transponder that can only be reset and reset by the dealer's service department, fob which is generally the only manufacturer with the tools needed to accomplish this.
