Key Fob Replacement and Repair
Modern car key fobs are utilized a great deal and are often misused. Many times just a simple repair or replacement is all that's required to restore them to working order.
The majority of fobs are made with flat watch-style batteries, which are readily available in hardware stores and auto parts retailers. However, before calling an expert, try a few DIY solutions!

It is common to find the latest key fob batteries in the auto parts section of a large box retailer or online. The majority of these batteries are CR2032 and CR2025 and are available in packs of 2 or more. Consult your owner's guide before you shop for the right battery.

Weak Signals
If your key fob doesn't respond to the buttons on the remote it could be a sign that the signaling system is not working properly. Radio signals are used to communicate between your car and the key fob. Weak or inconsistent radio signals can result in low performance and limited range.
Checking the battery level of your fob is a good idea, because it could have a significant impact on signal sensitivity. Resetting the settings of the fob can also help restore a more regular response. The procedure will differ from vehicle to vehicle. Your owner's guide or a phone call to your manufacturer's support number is your best guide.
Other factors, such as interference from other devices that operate at the same frequency can also cause weak signals. Other key fobs as well as wireless communication devices can interfere with the signal RF (radio-frequency) signals your key fob transmits to connect to the vehicle's receiver.
Damage to your keyfob's physical structure can also interfere with the transmission of radio signal, resulting in lower performance and less range. A blown fuse, broken or cracked buttons, or a bent fob case could interfere with the transmission of signals and cause the remote to fail to respond.
