Remote Key Fob Repair
Modern vehicles are equipped with a remote key fob that can be used to lock, unlock and start the vehicle. However, as with any piece of modern technology it is not without its own issues.
These are usually very easy to fix. It is as easy as resetting it which you should be able do by following the instructions for resetting in your owner's manual.
Check the Battery
The remote control is powered by the battery that is in a key fob. The battery is a small piece of equipment that has to be replaced frequently to maintain the functionality of the key fob. There are many other reasons your key fob might not be working besides the battery. This could be due to physical damage, water exposure or internal component failure. If your key fob has stopped functioning, replace the battery.
First, make sure you have the right size battery. Almost all modern key fobs are powered by a common three-volt CR2032 battery that's easily available at many stores. Most of these batteries are stamped with the size on one of the edges of the fob. A quick search for the name of your car's brand should help you locate the specific type of battery you need.
Once you have the proper battery then carefully open the key fob and remove its existing battery. Photograph the inside of the fob prior to you do this to ensure you put everything back together correctly. This simple step will save you from purchasing a new fob because you made a mistake when making it back together.
You should also be aware that some key fobs have a backup mechanical key, referred to as an emergency blade. The key blade is inside the key fob, and it lets you open the door to the driver's side of your vehicle in the event that the remote control fails. To open the blade of the key, you must locate the notch in the middle of your fob. The notch is typically covered by the plastic casing of the fob.
If you want to be extra cautious you can make use of a multimeter to test the voltage of the battery. The majority of modern key fobs have an voltmeter in their casings, however you can also purchase a multimeter for a few dollars from most hardware stores. The battery should generally read at 3.0 volts or more. A reading that is lower than this could mean that the battery is on its last legs and should be replaced immediately.
Check key repairs might look like high-tech, fancy convenience items but keys for cars aren't indestructible. These remote devices can stop functioning after a period of time, especially when they are frequently used or if they have been subjected to physical abuse. Fortunately, a majority of the time it can be easy to determine and repair a problem with the remote key fob and changing the battery is typically all that is required.
The majority of modern car key fobs have multiple buttons for different functions like locking and unlocking doors as well as activating the panic button, as well as opening the trunk. When a button is pressed the fob sends out a radio signal with the code that is interpreted by a receiver located inside the car. Some fobs have an option to start the car, which is particularly useful during cold winter mornings as well as hot summer days.
Typically, the buttons of keys can be reset by taking the device apart and ensuring they're not broken or stuck. The battery connector terminals of the key fob can get loose in time, even though they aren't intended to be removed. If the buttons' contacts have been disconnected from the circuit board and need to be soldered, a simple job is enough to put them back into place and restore the fob to its full functionality.
In addition, if the fob has been damaged or dropped in some other way, the buttons might be damaged or displaced from their alignment or otherwise misaligned. These problems are more difficult to repair on your own. However an auto repair shop in your area can fix them using the right tools and experience.
It's always an excellent idea to have a spare fob somewhere in the event that one of the ones you regularly use stops working. This will to avoid being stuck without your keys or having to pay a large amount of money to get the vehicle towed back to the dealer. Check your car insurance or car club membership or extended warranty coverage to determine the cost of replacing the key fob.
Check the Casing
It's not common for a key fob to get submerged, whether from a pool, a rainstorm or even your washing machine. The moisture that results can trigger a myriad of issues with the electronics. The good part is that keys can typically be saved from the brink of death by drying out thoroughly and following a few easy steps.
First, make sure that the buttons still work properly. This usually means removing, cleaning and reassembling the buttons. If the buttons do not pop back in or are stuck, it's time to replace the remote.
Examine the case to make sure that there isn't any obstruction to the operation of the key fob. Use tweezers or pliers to open the case and take out the battery, but don't disassemble the circuit board or antennas. If you disturb the circuits that keep your key fob programmed, you will need to visit an Interstate All Battery Center or dealer to reprogram it.
After you have removed and replaced your battery, it is a good idea for you to dry the key fob out by placing it into an airtight bag that contains silica gel packets. This will help prevent future issues with moisture and will help your key fob last longer.

After you've replaced the battery and reassembled your key fob, it's now time to test out its connection to your vehicle. This can be accomplished by inserting a small flathead screwdriver in the notch on the bottom of your key fob. Then, you can break the two halves of your key fob and then gently remove the circuit board. Be careful when inserting a new CR 2032 3V battery, ensuring that it's placed with the negative side facing downwards. After you've inserted the circuit board, you can put it back together and try again.
