Key Fob Repair Service
Key fobs can be subjected to a lot of abuse. Buttons can get stuck or break based on the way they are stored and how much they are jostled.
Luckily, most key fob issues are relatively simple to fix. Some key fob issues are more serious and require professional assistance. This is where locksmiths come in handy.
Dead Fob Battery
The key fobs for cars are quite intelligent However, that doesn't mean that they don't occasionally become stuck in the "not responding zone". When this happens, it's time to replace the battery. However, this doesn't always fix the issue, since you may also have an issue with one of the battery connector's terminals.
Automobile manufacturers are aware of this potential issue, and they frequently put a spare mechanical key inside the fob in case of such an emergency. To access this, find the small release switch or latch behind the fob (check the user manual for specifics). Pressing this will allow you to open the fob and access an actual key that you can use to unlock your vehicle.
Another indication that your fob's battery is dying is the fact that you have to be much closer to the car to unlock and open it than before. This is due to the fact that the fob's transmitter weakens when its battery dies and limits its range of operation.
It's fairly easy to replace the battery. You will need to purchase a button-cell battery (which looks like an elongated silver coin) and follow the directions in the user's guide to remove the old battery. After that, replace the new battery in the same direction that the old one was inserted (the positive side should face upwards toward the buttons). Test the lock/unlock and start the functions of your fob after reassembling it. Make sure the new battery is installed correctly.
You can unlock some key fobs by locating the latch, screw, or switch on the back and then prying the fob apart. You'll need the fob to work with your vehicle, so make sure not to harm it! You can also take the fob to an expert in case you're not comfortable making the change yourself. Since it's a common service the majority of auto shops will change the battery inside a fob for a nominal fee. Some dealers will even offer it for free, depending on the model and brand of your vehicle.
Fob Is Not Working
Replace the batteries if the key fob isn't working. This is the easiest solution and will fix the problem. If your device does not work after changing the battery it could be due to damage.
Damage can occur to the car key fob for many reasons including physical trauma, exposure to water or a corroded circuit board. These issues can stop your key from transmitting the signal to the receiver in your car, which will stop your car's ignition or doors from unlocking. If your fob is damaged, it's likely that you'll need a professional to repair or replace the component or the entire device.
The buttons on your keychain may have worn away with repeated use. The rubber can wear away making the buttons less 'clicky' or springy. They may also cease to register your presses. You can try wiping the buttons and adjusting them to see if this fixes the problem However, it's generally best to take the fob to a professional assessed for more extensive repairs.
Check that the battery you're using is exactly right for your fob. You can find a list of acceptable batteries online or at many hardware stores. You must always consult the owner's manual or the engraving on the inside of the fob to determine the type of battery it needs. A battery that isn't an ideal match could have issues transmitting powerful signals or providing sufficient power to the fob's internal components.
In rare instances, it could be that the issue isn't with your key fob, but more with the vehicle's receiver or electronic components. You can test this by using a physical key to open the door, and then trying to start your vehicle using the inductive backup system (if there is). If the physical key you have isn't able to open or start your car check with a mechanic the receiver and electronic components of your vehicle to determine whether they're functioning properly.
Fob Is Damaged
A key fob is made up of numerous components that function together and a single malfunction can cause others to fail. If a key fob stops working it's important to examine whether there's an obvious cause such as a damaged case or a broken internal component. It's also crucial to examine other components of the vehicle like the lights and horn to determine whether they're working as expected.
If the fob for your key is damaged, it's best to find a replacement at your dealership or an auto locksmith instead of attempting to fix it. It may be necessary to reprogramme the fob for the car. This is not something you can do at home, and requires special equipment.
Over time, the contacts on the buttons of a key fob can wear out. This is especially true if you drop the fob or leave it outside in hot weather.
As time passes the internal wiring of a key fob can also wear down. This could result in the button not functioning when it's pressed, or only functioning when it's pressing very hard. This can also result in the vehicle not being able to start or unlock after the fob is pressed.
The majority of fobs have the cover of plastic that can be opened up and then cleaned with water and soap. This can often help restore a key fob's proper function and it's a great practice to clean it often to prevent dirt from damaging the insides.
A bad battery is the main reason why the key fob won't start or function. Many mechanics and dealers can replace the battery quickly. If you're confident in installing the battery yourself, you can purchase the new one from an online store or a hardware store, and follow the directions on YouTube or in your owner's guide.
The worst-case scenario is that the key fob has internal damage, like cracks in the case, teeny electronic components not completely attached to the circuit board or corroded or bent battery contact points. If you observe any of these problems, you should consult an auto locksmith or a dealer to get a replacement key fob as well as assistance in programming it to your vehicle.
Fob is not programming
The car key fob is a convenient way to start your engine and open the doors of your vehicle. When they stop working, or fail to function, they can be frustrating. In some cases the issue could be as simple as replacing the battery but in other cases it may require an even more complex repair. The first step is to identify why the fob doesn't work properly.
One of the main reasons for a malfunctioning remote is that it no longer recognizes your vehicle. This can happen if the connection between your remote and the car is broken. You may be able to reset the connection without having to call a key fob repair service.
Other issues can occur when the key fob isn't able to sends a clear signal. This can occur if the key is damaged or the battery is dead. In either case, you should attempt to reconnect the key with your vehicle. This can be accomplished by following the instructions that came on the key fob. You should also keep a spare car key in the event that your primary key fails.
The fob might not be receiving a strong signal from the vehicle. This can be caused by a weak car battery, interference from wireless devices, or an antenna problem. Using a remote tester, you can test the fob to determine if it's the cause of the issue. If the tester doesn't light up when any of the buttons are press, the battery might need to be replaced or the fob could be broken.
A car's immobilizer could also prevent a fob from sending a clear signal. This could happen when your key fob hasn't been properly programmed or you have a software issue.
If you are unable to fix the fob or it isn't worth the trouble to try to repair it, you need to purchase the new one. You can find low-cost options from many online retailers and some can be delivered directly to your doorstep.
