11 Ways To Fully Defy Your Car Key Fob Replacement
Car Key Fob Replacement

A lot of cars today use key fobs that lock and unlock doors and start the car. Typically, replacing a standard fob will require a visit to the dealership and the cost is according to the vehicle's make.

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

Battery

The first step to take if the key fob you have is not working is to change the battery. These devices are replacing traditional keys, do more than lock and unlock the car. They emit a coded sequence of signals based on many times you press them. This signal is sent to a receiver within the car, and it locks or unlocks it. Fobs can break into pieces over time as does any other electronic gadget that you carry around in your pockets or purse.

If you're lucky your dealer has replacement batteries for keys fobs that are compatible with your car. If not, they are available at auto parts stores or even big-box retailers. You'll typically need a CR2032 button cell battery which ranges from $2-4 American for a pack of two. To avoid damaging the electronic circuit board, you'll need to remove the battery that was on your key fob and replace it with a new one.

Some of the newer fobs include a tiny key that can be pulled out if your keys don't work to open the door or start the car. This is a useful feature but can be dangerous for people who are prone to losing their keys. Some people utilize a wireless remote locking system that relies upon an RFID chip embedded into the key fob. If you have trouble with this, it's best to contact your car's manufacturer to determine whether the chip could be reset, or contact a locksmith if needed.

If you can purchase an extra key fob for a price you're comfortable with, you may be able to do the programming yourself. This is typically a less expensive option than buying a new key from a dealer. However, be warned that not all replacement keys from the aftermarket will work with your vehicle, and that most require specialized equipment to program.


Programming

Modern cars are usually equipped with electronic keys that let you unlock and start your vehicle remotely. If you lose yours or need to replace it you might be capable of programming the replacement yourself. Instructions are usually available on the internet. The exact procedure is contingent on the model of your vehicle. Some owner's manuals also contain specific programming instructions. Make sure that your key fob has new batteries before you attempt to program it. They are cheap and simple to replace, but the battery that is exhausted could cause problems with the process. It is also a good idea to close all doors because even a door left open could influence how the fob works.

To reprogram a remote key switch off your vehicle and take out the ignition key that was originally used. Press the lock button of the new fob within the same time frame generally between 10 and 30 seconds. The car may respond by turning the locks on and off, turning on the lights or chiming to confirm that the fob was programmed. Repeat this process for any additional keys you'd like to add to the system of your vehicle.

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

You can save money by using an automotive locksmith. Many dealerships charge a flat rate for this service. They have the equipment to complete the task for only a fraction of what you'd pay in the dealership. They may even be able to come to your location to perform the work.

Ask the dealer how much the service will cost and if they provide a guarantee. Check your warranty, auto club membership, or insurance policy to determine whether they cover lost fobs. If you have a good relationship with your mechanic, they may even let you know their pricing for this service prior to scheduling an appointment.

Dealerships

If you lose your car keys, you might be tempted to go to the dealership to obtain an alternative. Dealerships can charge more for this service than other locations, and they might not offer the best deal. Locksmiths and hardware stores are two other options for replacing your key fob. These are typically cheaper than a dealership and could save you lots of money.

A car key fob is a piece of technology that allows you to unlock and start your car without the need for a traditional key made of metal. It's a rectangular or oblong piece of plastic that has buttons that allow you to lock and unlock your vehicle, set off an alarm or open the trunk. Fobs gained popularity in the 1990s and are currently standard on a variety of automobiles. They can be a convenient way to unlock your car, however they also make it easy for thieves to steal your vehicle.

The most popular car key fob type is the push button starter. It is connected to your car's ignition. They can be located at an auto parts store or dealership. Other types of car key fobs include switchesblade keys, that house the key inside a piece of plastic and keyless entry fobs. The latter are the most sought-after because they permit you to open and start your car without a physical key.

Many dealerships inflate prices for key fobs since they know consumers will pay whatever it takes to get their vehicle back. Although it's difficult to find a low-cost replacement for a fob, you can save money by selecting the right replacement battery and using an alternative method of reprogramming the device.

If you have a traditional metal key a push-button starter or one of the newer smart keys, you can get a replacement for it at a locksmith that isn't associated with any specific car manufacturer. These locations offer a wide selection of replacement keys, and are able to cut and program them for less than dealers. You can use the search engine to locate a locksmith that is independent near you.

When your key fob goes missing, you'll likely need to pay a professional to replace it. However, it might not be as cheap as you think, particularly if the key fob includes an intelligent feature such as an automatic locking system or a remote start button.

Most modern cars have smart keys that are designed to prevent theft by sending unique security codes each time a button is press. These codes aren't stored on the fob itself, but rather in an embedded chip that communicates with the car to unlock doors and even start the engine. Because of this additional layer only locksmiths and car dealership technicians have the tools and know-how required to reprogram these keys.

You may be able to purchase a new keyfob at an establishment like a hardware or locksmith that specializes in security for cars at a lower cost than you would pay if you bought it through a dealer. But, you'll most likely require a professional to program the fob, which could require the same equipment that the dealership uses.

Some automakers offer instructions for doing-it-yourself fob programming in their owner's manuals or on the internet. These steps can be difficult and you may require another key fob to complete the process. It is advisable for both the owners and tenants to have two key fobs working before they lose one.

If your car has a traditional key shank in addition to the smart key it is possible to purchase a spare key at a key or hardware cutting store for a relatively low cost in the event that the metal key isn't lost together with the fob. Fobs that have transponders on both the key shank as well as the fob might need to be programmed by a professional, however this can be costly in the event that you need to make more than one spare or if your key requires replacing.

For those with German automobiles, for instance those that come with a "flip" function which is akin to a switchblade knife, might only be able to find replacement fobs at the dealer. The reason is that these fobs usually use an exclusive transponder that can only be reset and reset by the dealer's service department, which is typically the only company that has the necessary equipment to do so.
