Car Key Fob Replacement Cost

Key fobs today do more than simply unlock your vehicle and start the engine. They can also be used to perform other tasks such as remote starting or locking of the trunk.

In contrast to standard keys made of metal, these remotes aren't indestructible and can cost the earth to replace. The cost is determined by several factors, including the make and model of the remote and its location and retailer.

Keyless Entry

A lot of cars come with key fobs which can lock and unlock the doors and start up the engine in response to proximity. Some models have even advanced features, like remote parking. Certain models have buttons that allow you to roll down the windows. This is helpful on hot days, or when keys are inside.

The cost of getting an updated key fob to work with your vehicle is a cost that you should factor into your budget. Some dealers charge up to $150 for this service. Some charge less, however you may need to pay for a locksmith or equipment to program.

The latest key fobs include rolling code encryption along with other security measures to prevent thieves from copying and hacking codes that are transmitted between the fob and the receiver inside your vehicle. These systems are designed so that each transmitter receives a fresh code every second, making it almost impossible for a single transmitter to open a car door. The code your fob transmits is a combination of the 40-bit codes it receives from the transmitter and an operation code that informs the receiver of what to do, for example, locking or opening the trunk.

It's essential to have two key fobs if possible, and if you do lose one, it's best to get a replacement as fast as you can. Go through your owner's manual, auto club membership, or roadside assistance to determine whether they will cover the cost of a replacement fob. Resource , like bumper-to-bumper or extended warranties, could provide replacing a fob.

Remote-locking devices are the simplest type of remotes. The more sophisticated fobs come with a mechanical key and an immobilizer chip and other features. Some even come with a switchblade configuration so that you can tuck the key blade inside the fob when you aren't going to use it.

Remote Start

It is very convenient to be able to start your vehicle from the comfort of your office or home. You can cool your car's interior or warm it up on a cold winter's day. Depending on the system you have you can operate from a distance of hundreds of feet, or even across an entire parking lot.

Remote starters transmit a signal to components of the ignition system through the key fob. The majority of systems utilize a separate radio frequency that is specific to the vehicle, and they're typically encrypted to protect against hacking. This means that a thief must know the exact number in order to gain entry into your car and start it. A majority of these locks are locked after the engine starts in order to ensure that if anyone gains access, they won't be able to leave the vehicle.

Remote starters can also activate the climate control system in your vehicle. From power windows to heated mirrors, rear defrosters and more, these systems can be controlled by your remote fob. The system can be programmed to shut off after a certain time that helps reduce the risk of a battery drain. Some systems integrate with the alarm system of your vehicle and can notify you in the event of attempts to alter the system while it is running via remote start.

While it is possible to install a remote start system by yourself, hiring a professional installer is the best method to ensure you're getting everything working properly. These systems are extremely complex, and a simple mistake could cause serious damage. A DIY installation could also void the warranty.

A reputable installer makes use of high-quality equipment for remote start that is compatible with most vehicles. Installers will also tailor the system to fit your vehicle so that you benefit the most from the feature. Additionally, they'll assist you in understanding your budget and timelines to help them create the best plan for everyone.

Trunk Release

Car key fobs do more than unlock doors or start engines; they also double as convenience features and theft deterrents. They're also expensive to replace in the event of loss or stolen.

The most expensive fobs to replace are those that have an immobilizer and communicate with the car's computer. According to Mel Yu, automotive expert at Consumer Reports, these are basically "smart key" devices that combine mechanical key technology and transponder technology. He has reported that replacement fobs for such devices can cost up to $400, which includes programming.

The most popular type of fob to use is an in-car keyless remote which can control the trunk release, as well as the door lock and start functions. These are usually cheaper to replace, but the process can be expensive if you're dealing a dealer that wants to charge you for the entire service.

You can buy generic fobs for a fraction of the cost in numerous hardware stores. They are also available online and in many brick-and-mortar automotive stores. However, they do not have the same encryption technology that safeguards your vehicle from theft and misuse of the fob by unauthorized users. They might not be compatible.

Most modern cars have a hidden, emergency trunk release, that isn't always available in the case of a loss or break-in. A quick search in the owner's manual will reveal the location of this feature, which can be activated by pressing a lever or a switch close to the trunk latch. If you're unsure where the emergency release is located or if you are unable to locate it then ask your mechanic to look for it.


An effective way to avoid the cost of replacing your car key fob is to make it a habit to keep a spare key fob in your bag or pocket at all times. You can also reduce your chances of getting into a car accident by not leaving the key fob in the ignition when you're in the trunk, and also never locking your keys inside the car while at home or at the grocery store. If you do encounter a situation where you have to purchase a new fob, consult your local locksmith or retailer before going to the dealership. They may be able to help.

Folding Wing Mirrors

Folding mirrors are a great benefit especially on narrow streets where you might run into another vehicle. They can save some inches by folding inwards while you park and then out when you open your door. These are more common in European, Asian and North American car markets where parking spaces tend to be smaller. Why aren't they a standard feature in all cars, however?

If you own a car with power-folding mirrors, you may have to resynchronize them following changing the position of your key fob or locking and unlocking the car. A simple push of the button or turn of the control knob will do the trick. You'll hear a click to inform you that the mirrors have been synchronized.

Another exciting feature that automobile manufacturers are offering is the capability to summon your car by a press of the button on your key fob. This feature is similar to Tesla's summon feature, and could be particularly useful if you have a car that is difficult to park.

Certain fobs also permit you to roll down the car's window. This is a nice feature in hot temperatures and can help you to avoid insects while you're at a stoplight or waiting to go into your driveway.

Some retailers will program replacement keys for automobiles like the Volkswagen Tiguan or Honda Accord. However, the majority of dealers require you to visit the dealer in order to replace or program the keys. This is because certain fobs come with more advanced features or are part of an integrated security system that only the factory is able to offer. Still the dealers we talked to told us they're not afraid to reprogram aftermarket fobs.
