Dead coin battery
If the unlock button on the key fob isn't working, or if the unlock button does not work, it could be that the battery in the coin is damaged. Battery life should be between three and four year with regular use. However, it is possible for it to suddenly die. Fortunately, most car manufacturers have built-in fail-safes that ensure you are able to unlock and start your car even if the key fob is dead battery.
The battery on the key fob is held in place with clips made of metal, which complete a circuit. If these are worn or dirty, the battery may not receive power. The battery must also be of the correct size and type. If the battery is too small or large, it will not fit in the fob and won't work properly.
Key fob batteries are sold under many names, including CR2016 and even CR2032. They cannot be interchanged. Read the owner's guide for your particular model or look for a sticker on the fob that contains the details.
When you've got the proper battery and it's replaced, it's possible to replace it within a matter of minutes. Most fobs have a slider, switch, or gap that can be used to pry open the cover to swap out the original battery for a new one. Make sure the new battery has the same voltage and that it is placed in the correct direction.
Water damage
Even even if your key-fob has survived the wash cycle or taking a dip in the pool, water isn't suitable for electronics. It can harm the chip and damage a battery. There are some things that you can do to limit the risk of damage.
It's crucial to first eliminate the battery and then dry out the interior as possible. You can also clean the battery by using a cotton swab, which has been submerged in 90 percent alcohol.
After you have cleaned the key fob, you must let it dry for a few days. You can speed the process up by placing it high on a shelf to ensure it doesn't get smashed. Once you're sure it's dry, try replacing the battery and operating it in the same way as you normally would.
If the key fob still doesn't work, you may have a malfunctioning receiver module that's not transmitting signals to your vehicle. This can be quite expensive to fix, but it's worth trying if you want to avoid a costly replacement.
The easiest method to fix a broken key fob is to change the battery. Changing the battery should bring back the radio signal and make the key fob to work as it should. If the issue persists, you should seek assistance from a professional.
Receiver module that is defective
In certain cases there are instances where a flaw in the receiver module of the key fob might cause it to stop receiving or transmitting proper signals. In this case, the car will not recognize the remote control key. It will not unlock or start. In this case the replacement remote control will be required.
The steps needed to reprogram a key fob vary by make and model So, make sure to consult the owner's manual prior to trying to do it yourself. First, ensure that the battery in the key fob is in good working order and that all of its buttons are functioning. Close the doors and take out any aftermarket devices such as alarms or radios out of the vehicle.
You can also clean the chip with isopropyl or electronic cleaner. If the chip is in a state of disintegration it is likely to need to be replaced.
After you've cleaned the key fob, remove its circuit board. Clean the contacts with alcohol swabs and allow them to dry. After the contacts have dried, you can reassemble the key fob and test it. If it doesn't work, you may need to replace the battery. Choose a new battery that has the same voltage level that the original battery. It is recommended to double-check that the battery is in place in the first place, since the contact points can be extremely sensitive.
