Most fobs utilize flat watch-style batteries, which can be found in auto parts retailers. But before you call a professional, try a few DIY fixes!
Dead Key Fob Batteries
The battery for the key fob power the remote function of your car. It also, in conjunction with push-to-start vehicles, allows it to start your engine. It is therefore important to keep a functioning healthy and a good battery. A dead key fob can be an issue when you're on-the-go.

It is common to find an updated key fob battery in the auto parts section of a large box store or on the internet. Typically, they're CR2032 or CR2025 batteries and are available in packs of two or more. However it's a good idea to consult your owner's manual before you shop for the correct battery for your vehicle. Certain cars require a certain size or type of battery that isn't always readily available at big-box stores. Be sure to research before you buy.
Typically the battery is placed on the back of your key fob and can be removed by prying the case open using the flat-blade screwdriver. It will usually resemble a small coin and be labeled with the battery size. Make sure to note the orientation of the plus and minus signs in order to place the new battery properly.

Weak Signals
If your key fob isn't able to respond to the buttons of the remote it could indicate that the signaling isn't functioning correctly. Your car and key fob depend on radio signals to communicate, therefore weak or inconsistent signals could cause poor performance and range.
One of the first things you should determine is if your fob's battery is low since this can greatly affect the sensitivity of your signal. Resetting the settings on the fob could aid in restoring a more regular response. The procedure will differ from vehicle to vehicle. The owner's guide or a call to your manufacturer's support line is your best resource.
Other factors, like interference from other devices operating on the same frequency can also affect weak signals. Power lines, 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 interfere with the transmission of radio signal, resulting in low performance and a limited range. A damaged or blown fuse, a broken or cracked button or a bent case can affect the transmission of signals and cause the remote to fail to respond.
There are a few easy steps you can follow to try and resolve the issue of weak signals from your fob, 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.
Lastly, don't forget that if you have a spare key fob that is included with your vehicle, it can be used instead of the primary remote in the event that it starts to fail. It's worth trying this solution to see if it can solve the issue prior to investing in the new one. In this situation it could be the right an appropriate time to consult an expert auto-locksmith. They'll be able to identify the issue and recommend the best method of action.
Physical Damage
Key fobs may have issues from time to time. Luckily, the majority of these issues aren't serious or complex and can be fixed with some simple steps. It's important to have spare batteries or an additional fob in case one of your keys ever ceases to function.
The most common reason for car keys not working is the battery is dead. These tiny devices are powered by lithium-ion buttons or coin cell batteries.

You can open your fob's casing using a flat head screwdriver and gently remove the battery. Ensure that it is not damaged or loose and then put in an alternative battery. Most fobs require CR2032 batteries. However, yours may require a different type.

Keep the fob out of water or other sources of damage while you are experimenting. The fob is a durable device but you need to take care with it to make it last as long as it can.

Lost Fob
Even with the best care it's a fact of life that car key fobs will sometimes cease to function. It can be expensive to replace yours if you lose it, especially if you do not have an extra. "You could end up paying $50 to $100 for a replacement, and having it programmed by a dealer, and an electronic backup that could cost you another $100," says Mel Yu an automotive analyst at Consumer Reports.
A weak battery is one of the most frequent reasons for a keyfob to stop working. If you are aware of how to replace the battery, or if your owner's manual has instructions, you can attempt it yourself. But if that doesn't fix the issue, it's time to get help from an expert.
A locksmith can be capable of helping you locate the lost fob or have it replaced. They'll also have a good idea of why your fob stopped working in the first instance. If your car is older and does not have smart technology built in, you can still save money by recording the key number plate on your mechanical backup key. It's typically hidden behind a keychain with an ornamental design. This can make it easier for the locksmith to reprogram a new key fob for your car if you ever need to do so.
If your key fob is an older smart key, it will need 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, which prevents thieves from gaining access to your car. This means that the locksmith has to have a special programing tool that is only available to car manufacturers, which increases the cost.
In the majority of cases, the whole service will be charged at the same time. This includes all costs to reprogramme a new keyfob. Depending on the type of vehicle, that can run from around $20 at certain stores to $200 or more at a car dealer.
