Key Fob Replacement and Repair
Modern car key fobs are utilized frequently and are often abused. Many times an easy replacement or repair is all that's required to bring them back into working order.
Most fobs use flat watch-style batteries, which can be found in hardware stores and auto parts retailers. But before you call an expert, you can try 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 cars it will start your engine. Therefore, it is critical to maintain an efficient, functioning battery. A dead key fob is a major problem when you're on-the-go. A simple, inexpensive replacement will fix the problem quickly.

However it's best to consult your owner's manual before shopping for the right battery for your device. Certain vehicles require a particular size or type of battery, which is not always available at big-box stores. Be sure to research before you buy.
The battery is typically located in the back of the key fob. It can be removed using a flat-bladed screwdriver by prying the case open. It is usually shaped like an ordinary coin and will be marked with the battery's size. Be sure to note which way the plus and minus symbols are positioned to ensure that the new battery is positioned correctly.

Weak Signals
If you notice that your key fob isn't responding to buttons on the remote, this can be an indication of a problem with the signaling. Radio signals are used to send messages between your car and key fob. Inconsistent or weak radio signals can lead to poor performance and a limited range.
One of the first things you should examine is whether your fob's battery is low, as this can significantly affect the sensitivity of your signal. It's also advisable to reset the fob's settings that can help bring back an even and consistent response from the car. The procedure varies from vehicle to vehicle, so the owner's manual or call to the help line of the manufacturer is likely to be the best source of information here.
Other factors, such as interference from other devices that operate at the same frequency can also contribute to weak signals. Power lines as well as other key fobs, wireless communication devices, and even cell networks can disrupt the RF (radio frequency) signals that your key fob utilizes to connect to the receiver in your vehicle.
Physical damage to your keyfob can also affect the transmission of RF signal, resulting in low performance and a limited range. A blown fuse, broken or cracked buttons or a bent case can interfere with the transmission of signals and cause the remote to not respond.
There are some simple steps you can follow to try and solve the issue of weak fob signals, such as resetting the fob's settings, or replacing the battery. If your fob is old and worn, it could be time to replace it.
Don't forget to use the spare remote that came with your car in the event that your primary remote starts to fail. It's worth trying this option to see if it can solve the issue before you invest in an entirely new one. If not, it could be the right time to contact a professional auto locksmith. They'll be able to identify the issue and recommend the best course of action.
