Dead Key Fob Batteries

Make sure to consult your owner's manual prior to you purchase the correct battery. Certain vehicles require a certain size or type of battery that isn't always in stock at big-box retailers So, make sure you be aware of the correct specifications before you purchase.

The battery will appear like tiny coins, and it will be identified according to its size. Be sure to note which direction the plus and minus symbols are positioned to ensure that the new battery is properly placed. After the battery has been replaced then gently snap the two pieces of the fob back together. Then test the buttons.

Weak Signals
If you notice that your key fob isn't responding to the buttons on the remote, this can be an indication of a problem with signaling. Your car and key fob depend on radio signals to communicate, therefore weak or inconsistent signals could cause poor performance and range.
Examining the battery level of your fob is a good idea because it could significantly affect the sensitivity of the signal. Resetting the settings of the fob can also aid in restoring a consistent response. The process will vary from vehicle to vehicle. Your owner's guide or a phone call to your manufacturer's support line is your best source of information.
Other factors, including interference from other devices that operate on the same frequency, can also cause weak signals. Other key fobs as well as wireless communication devices could interfere with the signal RF (radio-frequency) signals your key fob transmits to connect to the receiver of your vehicle.
Damage to your keyfob's physical structure can interfere with the transmission of radio signal, leading to poor performance and range. A blown fuse, damaged or cracked button, or a bent case of the fob may affect the transmission of signals and cause the remote not to function properly.
You can solve the issue by resetting your fob's settings or by replacing the battery. If your fob has become old and worn out, it might 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. You should try this solution first to see if you can solve the issue prior to buying an entirely new remote. In this situation it could be the right the right time to contact an auto-locksmith professional. They will be able to identify the issue and recommend the best course of actions.
Physical Damage
Key fobs can be troublesome occasionally. Fortunately, most of these problems are not difficult or complicated and can be fixed with some simple steps. It's a good idea to keep spare batteries or an additional fob in case your key stops working.
The most frequent reason for a car key fob not working is the battery is dead. These tiny devices are powered by lithium-ion button or coin cell batteries. These batteries are easily replaceable and can be found at most pharmacies and grocery stores. The fob's case can be opened using a flat-headed screwdriver and gently remove the battery that you have. Ensure that it is not loose or damaged and then simply pop in a new battery. Most fobs use CR2032 batteries. However, yours may require an alternative type.
The fob may also stop responding to the buttons when it loses its connection to the vehicle. This could be due to a variety of factors, including changing the batteries, but it is generally simple to get an auto Locksmith or your local dealership to resolve.

Lost Fob
Even with the best of care it's a fact in life that car key fobs will sometimes fail to function. It's costly to replace yours if you lose it particularly when you don't have an extra. "You may end up paying between $50 and $100 for a replacement, and having it programmed by the dealer, and an electronic backup that could cost another $100," says Mel Yu an automotive analyst at Consumer Reports.
One of the most common reasons for a key fob's device to stop working is a simple problem, such as a weak battery. You can try replacing the battery yourself when you know how, or get instructions from the owner's manual. If this doesn't resolve the issue, it's time to get help from an expert.
A locksmith can be able to help you find the lost fob or have it replaced. They will also likely have a good idea of why your fob was not 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 typically hidden behind a decorative keychain ornament) and storing it in a secure place, such as in your wallet or on your phone. This can make it easier for a locksmith to reprogram the 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 can cost more than replacing it. That's because modern key fobs employ rolling-code encryption to stop thieves from accessing the car. This means that the locksmith must use a special programing tool which is only available to the car manufacturer, which increases the cost.
In the majority of instances, you'll need to pay for the entire service at once, which includes any charges to reprogram the new key fob. Based on the car, that can run from around $20 at certain stores to $200 or more at a car dealership.
