Key Fob Replacement and Repair
Key fobs on modern vehicles do a lot of work and are subject to lots of abuse. In many cases just a simple repair or replacement is all that's required to bring them back into good working in good condition.
Most fobs use flat watch-style batteries, which are easy to find in hardware stores and auto parts retailers. Before calling a professional, do a few DIY fixes.
Dead Key Fob Battery
The battery of the key fob powers the remote you have in your car and, in push-to-start vehicles, it can start your engine. As a result, it is critical to maintain a healthy, working battery. A dead key fob is a major problem when you're in the middle of nowhere. A simple, inexpensive replacement will fix the problem quickly.
The most frequent sign that a battery on a key fob is failing is the decrease in signal strength and range. You might also notice that the buttons on the key fob aren't working or require extra effort.
A new key fob can be found in the auto parts section of a major retailer or on the internet. They are typically CR2032 and CR2025 and are sold in packs of 2 or more. However it's best to check your owner's manual prior to purchasing the correct battery for your vehicle. Certain cars require a certain size or type of battery that isn't always available at big-box stores. Be sure to research before you buy.
The battery is usually found at the back of the key fob. It can be removed using the flat-bladed screwdriver, by removing the case. The battery will appear like an ordinary coin and will be labeled based on its size. Make sure to note the orientation of the plus and minus symbols so that you can place the new battery properly. After the battery has been replaced and the fob is closed, gently snap the two pieces of the fob back together, and test the buttons.
It's important to note that if your key fob continues to cease functioning even after a battery replacement, it could be deprogrammed. In this case you will require a locksmith needed to help you. This will cost more than just replacing the battery in the key fob.

Weak Signals
If your key fob does not respond to the buttons on the remote it could be a sign that the signaling is not working correctly. Your car and key fob depend on radio signals to communicate, so weak or inconsistant signals can cause poor performance and range.
One of the first things you should examine is whether the battery of your fob is depleted since this can greatly affect the sensitivity of the signal. Resetting the settings of the fob can aid in restoring a more consistent response. The procedure varies from vehicle to vehicle, so your owner's manual or a phone call to the help line of the manufacturer is likely to be the best guide here.
Other factors, like interference from other devices that operate on the same frequency, can also cause weak signals. Power lines as well as other key fobs, wireless communication devices, and even cell networks can interfere with the RF (radio frequency) signals that your key fob utilizes to connect to the receiver inside your vehicle.
Physical damage to your keyfob can also affect the transmission of RF signal, leading to low performance and a limited range. A blown fuse, a broken or cracked button or a bent case of the fob can affect signal transmission and cause the remote not to respond.
You can attempt to resolve the issue by resetting the settings on your fob, or by replacing the battery. If your fob has become old and worn out, it might be time to replace it.
Don't forget to utilize the spare remote that came with your car if your primary remote begins to fail. It's worth trying this option to determine if it resolves the issue prior to investing in a new one. In this case it could be the right time to call an expert auto-locksmith. They'll be able to determine the cause and suggest the most effective solution.
Physical Damage
It's not uncommon for key fobs to have issues from time-to-time. Most of the time, these problems aren't complicated or severe and can be fixed by following a few easy steps. It's recommended to keep spare batteries or another key fob in the event that one of your keys ceases to function.
A dead battery is the most frequent reason why a key fob in a car is not working. These tiny devices depend on tiny lithium-ion button or coin batteries to function.

You can open the case of the fob using an screwdriver that is flat and gently pull out the battery that you have. Replace the battery, ensuring it's not damaged, loose or damaged. Most fobs utilize CR2032 batteries, however yours may require a different kind.
When your fob loses its pairing, it can stop responding to buttons. This can happen due to a variety of factors, such as changing the batteries, but it is generally simple for an auto Locksmith or your local dealership to fix.
If none of the methods above work, you can try this trick: unplug the battery from the car and fob for a few minutes and then connect them in a reverse order. This may cause the system to reboot, and in some cases, this will fix the issue without further steps.
While key fob repairs testing the fob, make sure to keep it away from water and other dangers. A fob can be pretty sturdy, but you need to treat it with care in order for it to last as long as you can.
