Key Fob Replacement and Repair
Modern car key fobs are used a great deal and are frequently abused. Sometimes, a simple replacement or repair is all it takes to get them back in working in good condition.
Most fobs are powered by flat watch-style batteries, which is easily found in auto parts and hardware stores. Before you call an expert, try a few DIY fixes!
Dead Key Fob Batteries
The battery in the key fob's remote powers the remote you have in your car, and in push-to-start cars, it can start your engine. As a result, it is essential to keep an active, healthy battery. When you're on the move, a dead key fob can be a huge problem. A simple, inexpensive replacement will solve the issue quickly.
The loss of range and signal strength are the most commonly observed indications that a battery on a keyfob is failing. It is also possible to notice that the buttons on your key fob aren't working or require more effort.
You can often find a new key fob battery in the auto parts section of a big box store or on the internet. They are typically CR2032 and CR2025 and are sold in packs of 2 or more. Make sure to consult your owner's manual prior to you shop for the right battery. Certain cars require a certain size or type of battery, which is not always available at big-box stores. Be sure to check before you buy.
The battery is usually found in the back of the key fob. It can be removed with the flat-bladed screwdriver, by opening the case. The battery will look like a small coin and be identified according to its size. Make sure to note the direction the plus and minus symbols are placed to ensure that the new battery is placed correctly. After the battery has been replaced, gently snap the two pieces of the fob back together and test the buttons.

Weak Signals
If you notice that your key fob isn't responding to buttons on the remote, it could be an indication of a problem with the signaling. Your car and key fob depend on radio signals to communicate, therefore weak or inconsistant signals can result in poor range and performance.
One of the first things you should examine is whether your fob's battery is insufficient since this can greatly affect the sensitivity of the signal. Resetting the settings of the fob can also aid in restoring a constant response. The procedure differs from vehicle to vehicle, so your owner's manual or a call to the helpline of the manufacturer is likely to be the best guide here.
Other factors, including interference from other devices operating at the same frequency can also affect weak signals. Other key fobs and wireless communication devices may interfere with the signal RF (radio-frequency) signals your key fob sends to connect to the receiver of your vehicle.
Damage to your keyfob's physical structure can affect the transmission of RF signal, resulting in lower performance and less range. A blown fuse, broken or cracked buttons or bent fob case can all affect the transmission of signals and cause the remote to not respond.
You can fix the problem by resetting your fob's settings, or by replacing the battery. If your fob is old and worn, it may be time to replace it.
Also, don't forget if you have an extra key fob that comes with your vehicle, this can be used in place of the primary remote in the event that it begins to fail. Try this method first to see if it can resolve the issue before buying an entirely new remote. In this case it may be the right time to contact an expert auto-locksmith. They can identify the issue and recommend the best way to proceed.
Physical Damage

A dead battery is the most common cause of a car keyfob not working. These little devices depend on tiny lithium-ion button or coin batteries to function. They are easily replaced and are available at most pharmacies and grocery stores. Open the fob's case with a screwdriver with a flat head and gently remove the battery you have. Check to see if it's damaged or loose and then simply pop in the new battery. Most fobs use CR2032 batteries, but yours may require a different kind.

You can try this trick to fix your fob if none of the above methods work: disconnect the battery from both the car and the fob for about 10 minutes, then reconnect them in the reverse order. This could trigger a reboot within the system, and in some cases, this alone will fix the issue without having to do any of the other steps.
Keep the fob away from water or other sources of harm while you're experimenting. Fobs can be quite durable, but it's important to take care with it in order for it to last as long as possible.
If none of the troubleshooting techniques above help, you may need to replace your key fob. If it's been dropped, trampled on or exposed to harsh environmental conditions, it may not be able to be repaired and may require an upgrade. If that's the case, be sure to search for a deal prior to making a final decision.
