Key Fob Replacement and Repair
The key fobs found in modern vehicles perform a lot of work and are subject to a lot of abuse. In most cases, a simple repair or replacement is all it takes to get them working again.
Most fobs run on a flat watch-style battery, which can be found in auto parts and hardware stores. Before calling in a professional, you can do some DIY fixes.
Dead Key Fob Battery
The battery for the key fob power the remote function of your car and, with push-to-start vehicles, allows it to start your engine. As a result, it is critical to maintain a healthy, working battery. When you're out and about, a dead key fob can cause a lot of trouble. The good news is that a simple, inexpensive replacement is able to fix the issue quickly.
The most frequent indication that a key fob's battery is depleting is the loss of signal strength and range. It is also possible to notice that the buttons on your key fob aren't working or require more effort.
A new key fob can be found in the auto part section of a major retailer or on the internet. Typically, they are CR2032 or CR2025 batteries that are sold in packs of two or more. However, it's a good idea to consult your owner's manual before shopping for the correct battery for your device. Some cars require a specific size or type of battery that isn't always readily available at big-box stores. Make key car repair to verify before you buy.
Typically the battery is placed in the back of your key fob. It is removed by tearing the case open with an abrasive screwdriver with a flat blade. It will usually resemble a small coin and be labeled with the battery size. Make sure to note the direction the plus and minus symbols are oriented to ensure that the new battery is positioned correctly. After the replacement battery is installed, gently snap the two pieces of the fob in place and test each button to ensure they work.
It's important to note that in the event that your key fob continues to cease functioning, even after a battery replacement, it could be deprogrammed. In this situation it is likely that a locksmith will be needed to help you. This is more expensive than replacing the battery of your key fob.

Weak Signals
If you notice that your key fob isn't responding to 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, and weak or inconsistent signals can cause poor range and performance.
One of the first things to determine is if your fob's battery is insufficient since this can greatly impact signal sensitivity. It's also worth resetting the fob's settings that can help get the same response from the car. The procedure differs from vehicle to vehicle, so your owner's manual or call to the manufacturer's help line is likely to be the best source of information here.
Other factors can contribute to weak fob signals, for example, interference from other devices operating at 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 inside your vehicle.
Furthermore physical damage to your key fob can affect the transmission of RF signals, which may result in poor range and performance. A blown fuse, broken or cracked buttons or a bent case can all affect the transmission of signals, causing the remote to fail to respond.
There are a few easy steps you can try to and solve the issue of weak signals from your fob, like resetting the fob's settings or changing the battery. However, if your fob is old and worn out, it's probably time to replace it altogether.
Don't forget to remember that if you have an extra key fob which comes with your vehicle, it can be used in place of the primary remote in case it begins to fail. Try this method first to determine if you can resolve the issue before buying a new remote. If not, it could be the right time to consult an experienced auto locksmith. They will be able to identify the issue and suggest the best way to proceed.
Physical Damage
It's not unusual for key fobs to have issues from time-to-time. Fortunately, most of these issues aren't difficult or complicated 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 ceases to work.
A dead battery is the most common reason why a key fob in a car is not working. These tiny devices are powered by lithium-ion button or coin cell batteries. They are easy to replace and can be found at most pharmacies, food stores, and other places which sell electronic items. You can remove your fob's shell with an screwdriver that has a flat-head and gently pull out the battery. Ensure that it is not loose or damaged and then put in the new battery. Most fobs utilize CR2032 batteries. However, yours might require an alternative type.
If your device loses its pairing, it could stop responding to buttons. This could be due to many factors including changing the batteries. However it is possible to fix the issue with an auto Locksmith or a local dealership will usually be able to solve the issue.
If none of the strategies above work, try this method: disconnect the battery from the car and fob for a few minutes and then connect them in reverse order. This can force a restart within the system and in some cases this will fix the issue without having to do any of the other steps.
Keep the fob out of water or other sources of damage while trying out new techniques. Fobs can be quite durable, but it's important to treat it with care when you want it to last as long as you can.
If the above troubleshooting tips don't help, it might be time to consider 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 will need an upgrade. If this is the case, you should be sure to search for a deal before making your final decision.
Lost Fob
Even with the best of care, car key fobs may fail 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 paying $50 - $100 for a new one and having it programmed by the dealer, and mechanical backups that could cost another $100," says Mel Yu an automotive analyst at Consumer Reports.
A weak battery is one of the most common causes for a keyfob's cease to function. Try changing the battery on your own if you know how or consult your owner's manual. If this doesn't resolve the problem, it's time to contact an expert.
A locksmith can be able to help you find your lost fob or get it replaced. They'll also probably have an idea of why your fob was not working in the first place. If your car is older and does not have smart technology built in it is still possible to save money by recording the key number plate of your mechanical backup key. It's typically hidden behind a decorative keychain. This will make it easier for the locksmith to reprogram a brand new key fob to your car should you need to do it.
If your key fob is an old smart key, it'll need to be deprogrammed by a locksmith or dealer. This can cost more than simply replacing it. This is because modern key fobs employ rolling-code encryption to prevent thieves from getting into the car. And that means the locksmith must have an exclusive programming tool that only the car manufacturer has, which increases the overall cost.
In the majority of cases, the whole process will be charged one time. This includes all costs to reprogramme a new keyfob. This can range from $20 in some stores to over $200 at car dealerships, based on the vehicle.
