Dead Key Fob Batteries

However it's a good idea to consult your owner's manual before shopping for the correct battery for your fob. Certain vehicles require a certain size or type of battery that's not always available at big-box retailers Be sure to know the specifications prior to you purchase.
The battery is usually located in the back of the key fob. It is removed using an abrasive screwdriver with a flat blade by removing the case.

Weak Signals
If your key fob isn't able to respond to the buttons of the remote, it could be a sign that the signaling system is not functioning correctly. Radio signals are used to transmit information between your car and the key fob. Poor or inconsistent radio signals can result in poor performance and range.
Checking the battery level of your fob is a good idea, because it could affect the sensitivity of your signal. It's also worth resetting the fob's settings and help bring back the same response from the car. The procedure may differ from vehicle to vehicle. The owner's manual or a call to your manufacturer's support line is the best resource.
Other factors can contribute to weak fob signals, including interference from other devices that operate on the same frequency as your key fob. Power lines, other key fobs, wireless communication devices, and even cellular networks can interfere with the RF (radio frequency) signals that your key fob utilizes to connect to the receiver in your vehicle.
The physical damage to your keyfob can also interfere with the transmission of radio signal, leading to low performance and a limited range. A blown fuse, broken or cracked button or a bent case on the fob may all affect the signal transmission and cause the remote not to respond.
You can try to resolve the issue by resetting your fob's settings, or by replacing the battery. If your fob has become old and worn, it may be the right time to replace it.
Don't forget to use the spare remote that came with your car if your primary remote begins to fail. It's worth trying this option to see if it solves the issue prior to investing in an entirely new one. In this case it could be the right the right time to contact a professional auto-locksmith. They'll be able to determine the cause and suggest the best solution.
Physical Damage
It's not unusual for key fobs to have issues from time to time. Luckily, the majority of these issues aren't complicated or a major issue and can be solved by following a few simple steps. It's a good idea to keep spare batteries or another fob in the event that your key stops working.
The most common reason for car keys not working is an inactive battery. These tiny devices are powered by lithium-ion button or coin cell batteries. They can be replaced and can be purchased at most pharmacies and stores. You can open your fob's shell with an screwdriver that has a flat-head and gently remove the battery. Ensure that it is not damaged or loose and then simply pop in an alternative battery. The majority of fobs use CR2032 batteries, however yours may require a different type.
Your fob might also stop responding to buttons if it loses its connection to the vehicle. This can be caused by various reasons like changing the batteries. However, an auto Locksmith or a local dealership is usually able to solve the issue.
If none of the methods above work, you can try this trick: disconnect the batteries from the car and the fob for a few minutes and then reconnect them in the opposite order. This may cause the system to restart, and in certain cases it will resolve the issue without any other steps.
Keep the fob clear of water or other sources of damage while playing around. The fob is quite robust, but it's crucial to treat it with care when you want it to last as long as it can.
If the suggestions above do not help, it may be time to think about replacing your key fob. If it has been dropped, trampled on or exposed to harsh conditions, it might not be able to be repaired and may require a replacement. If this is the case, make sure to search to find a bargain before making a final decision.
Lost Fob
Even with the best care it's a fact in the road that car key fobs will occasionally cease to function. If you lose yours, it could be a huge expense to replace it--especially if you don't have a spare. "You may end up spending $50 or more to purchase an equivalent replacement from a dealer and get it programmed, and a new mechanical backup which could cost you at least another $100," says Mel Yu who is an automotive analyst at Consumer Reports.
A weak battery is one of the most frequent reasons for a keyfob's device to cease to function. If repair car key know how to replace the battery, or if the owner's manual has instructions, try it yourself. If that doesn't work you'll need to call an expert.
A locksmith can be in a position to assist you in finding your lost fob, or get it replaced. A locksmith will probably know the reason your fob stopped working in the first place. And if your car is a model older than the one you own and has no smart technology built-in, you can save some money by finding the key number plate on your existing mechanical backup key (it's usually hidden behind a decorative keychain) and recording it in a secure location, such as your wallet or on your phone. This will make it easier for the locksmith to reprogram a brand new key fob to your car in the event that you need to do it.
If your key fob is an old smart key, it'll have to be deprogrammed by a locksmith or a car dealer. This could cost more than just replacing it. Modern key fobs are secured by rolling-code encryption that prevents thieves from gaining access to your car. That means that locksmiths need a special programing tool that only the car manufacturer has, which increases the overall cost.
In the majority of cases, the whole service will be charged at once. This includes any costs for reprogramming a keyfob. It can cost anywhere from $20 at some shops to over $200 at car dealerships, depending on the model of vehicle.
