Car Key Fob Replacement

Many vehicles use key fobs to lock and unlock doors and start your car. Replacing the standard key fob typically requires an appointment with the dealer who will charge you according to the model of your vehicle.

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

Battery

If your key fob isn't working the first thing to do is replace its battery. These devices that have replaced traditional keys, do more than lock and unlock the car. They emit a sequence of signals based on how many times you press them. This signal is sent to a receiver within the car, and it locks or unlocks it. Fobs are susceptible to breaking in time as does any other electronic device that you carry around in your pockets or purse.

If you're lucky, your new car dealer will have replacement key fob batteries that will work with your car. If not, they're available at auto parts stores or even big-box retailers. You'll want a CR2032 battery that is typically around $2-4 American per pack of two. To avoid damaging the electronic circuit board you'll have to carefully remove the battery that was on your key fob before replacing it with a new one.

Certain of the more recent fobs include a tiny key that can be pulled out if your keys fail to open the door or start the car. While this is a useful feature, it could be risky for those with the tendency to lose keys. Others utilize a wireless remote-locking system that relies on an RFID chip embedded in the key fob in order to operate the doors. If you are having trouble getting your car manufacturer's attention and ask if the chip could be reset. You can also call an expert locksmith.

You might be able to do the programming yourself if you can purchase a replacement key at the price you are comfortable with. This is typically a less expensive option than purchasing a brand new key from a dealer. Be aware that not all replacement keys from the aftermarket will work with your vehicle and require special equipment to program.

Programming

Modern cars are equipped with electronic key fobs, which let you start and unlock your car via the internet. You may be able to program a new key if you lose yours or if you require one. Instructions are generally available online. The exact procedure depends on the model of your vehicle. Some owner's guides 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 inexpensive and easy to replace, but an exhausted battery can interfere with the process. It is also a good idea to close all doors since even one door left open can influence how the fob works.

To reprogram a remote, turn off your car and remove the original ignition key. Press the lock button on the new fob within a predetermined time period, typically 10-30 seconds. The car might respond by switching on the lights, turning off the locks or emitting an audible chime as a confirmation that the fob is programmed. Repeat this procedure for any additional fobs that you wish to add to your vehicle's system.

Be aware that this reprogramming method only works for cars that use the same technology. If your vehicle has a different key fob, or has an ignition key that is different from the other, it will require specific programming. This is only possible by an authorized dealer.

You can save money by hiring an auto locksmith. Many dealerships charge a flat rate for this service. They have the tools to complete the task for a fraction what you would have to pay at the dealership. They may even be able come to you to do the job.

Ask the dealer what the service will cost and if they have the possibility of a guarantee. Also, check your new-car warranty, auto club membership or car-insurance policy to see if 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 the cost of this service prior to making an appointment.

Dealerships

If you lose your car keys, you may be tempted to visit the dealership to obtain an alternative. However, dealerships typically charge more than other places for this service, and they might not provide the best price. Hardware stores and locksmiths are two other options to replace your key fob. These stores are usually less expensive than the dealership, and can save you money.


A car key fob is a piece of technology that lets you open and start your car without using a traditional key made of metal. It's an oval or rectangular piece of plastic with buttons that allow you to lock and unlock your vehicle, set off an alarm or open the trunk. Fobs were popular in the 1990s and are now common on a variety of automobiles. They're a convenient way to open your car but they can also make it easier for thieves to steal your car.

The most common type of car key fob is the one with a push-button start, which is affixed to the ignition of your car. You can usually find them at the dealership or an auto parts store. Other kinds of car key fobs include switchesblade keys, which contain the key made of metal inside a piece of plastic, and keyless entry fobs. They are the most popular as they allow you to open and start your car without physical keys.

A lot of dealerships overcharge the price of key fobs because they know that consumers will pay for any service needed to return their vehicle. It's not always easy to locate a replacement fob at an affordable cost. However you can save cash by purchasing the correct battery and reprogramming it in a different method.

You can replace your key with an independent locksmith who is not associated with a specific car manufacturer, whether you have an old-fashioned, metal key or a sophisticated electronic key. They have a wide range of replacement keys and can cut and program them at cheaper than dealers. You can use the search engine to locate a locksmith who is independent near you.

Locksmiths

If your key fob is lost, you'll need to hire a professional to replace it. It may not be as inexpensive as you think if your key fob has a smart feature, like remote start or locking that is automatic.

Modern cars are equipped with smart keys that are designed to prevent theft by sending unique security codes every time the button is press. The codes are not stored on the fob itself but instead in an embedded chip that communicates with the vehicle to unlock doors and begin it. Because of this extra layer of security, it's only certified locksmiths or car dealership technicians that have the tools and know-how to reprogram replacements for these types of keys.

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

Some automakers offer instructions for self-programming fobs in their owners' manuals or on the internet. The steps are a bit tricky, though, and you might need a second functional key fob to speed up the process or even to complete it all. It's sensible for owners and lessees alike to have two functioning key fobs before they experience the disappointment of losing one.

If your car is equipped with a traditional key shank in addition to the smart key, you'll be able to get a spare made at a hardware or key cutting store for a relatively low cost in the event that the metal key doesn't get lost as is the fob. my sources with transponders on both the key shank as well as the fob might need to be programmed by a professional, but this can be costly if you want to make more than one spare or if the key requires replacing.

People with German cars, for example, that have the "flip" function, which is similar to a switchblade knife might only be able to find fob replacements at the dealership. This is because these fobs use a transponder which can only be reset or reprogrammed at the dealer service department.
