With a thumb nail, or a small screwdriver with a flat head (A) to lift up the key fob battery compartment cover (B). Replace the coin battery CR2025 and ensure it is fitted in the proper direction and polarity.

Dead Coin Battery

A dead battery on a coin is the most common reason of a key fob not locking or unlocking your car. It usually shows warning signs prior to dying like a lower range or no power at any time. It is simple to replace with a new one (CR2025) from a local supermarket. It is important to be aware that using the wrong or incompatible batteries could cause damage to your key fob. Make sure that the new battery is identical in size, specifications and voltage as the older one.

If your fob was exposed to clean water, such as rain or soapy tap water, it is likely that the electronic chip inside has been damaged by corrosion. You can clean the chip using isopropyl or electronic cleaners to see if this helps, but that the chip has been damaged.

The simplest solution is to get a new key fob. Major car dealers sell keys and can be installed by a skilled mechanic. You can also buy them online, such as on eBay. The best method is to work on a flat surface that has good lighting. This will make it easier to work on the small parts inside. You'll also be able to avoid putting something in the wrong location. Always keep your key fob in an area that is secure and safe.

Water Damage

It's possible to think that your fob is destroyed if drop it into a pool or accidentally wash it. But there's a way to salvage it. When the circuit board on the fob is exposed to water, it develops a conductor that shorts out the components. It also accelerates the process of rust and corrosion.

This is an easy fix. Find something absorbent to put inside the fob. A paper towel or tissue will be ideal. Then apply an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board and other components to clean out any battery acid residue or contamination. Allow the circuit board to air dry in a warm, dry environment for a few weeks.

When https://www.thekeylab.co.uk/seat-car-keys/ has dried out then replace the battery with another one of the same size and the same polarity ('+' with the upwards direction). It can be tricky to open the fob to access the battery but if you have a small screwdriver that is flat available, it should be able to slide into easily. After the fob is rebuilt, it should operate just as normal. If it doesn't work, you may have to program it again or replace the module.

Radio Interference

When a key fob working correctly, it sends the radio frequency signal which is picked up by the receiver module in your car. If the signal is interrupted in any way the key fob will not function properly. This could be due to objects or weather conditions, or other transmitters operating on the same frequency in close proximity to your vehicle.

This can cause your key fob to not be able to activate the vehicle's features like the ignition switch or the security system. It is best to replace your key fob's battery.

A few aftermarket LED lighting fixtures that utilizes the same frequency as a remote key fob could interfere with the signal and stop it from reaching the receiver modules. The LED's lighting needs to be turned off or switched to a different frequency in order to keep out interference.

If you've just replaced the battery in your key fob and the issue persists, it's likely that the antenna on the key fob is damaged or has stopped working. The antenna is responsible for transmitting signals between the key fob and the receiver module. Utilizing an OBDII scanner will help diagnose this issue by telling you what is wrong with the system. The scanner will ask for details about your car, including the make, model engine type, VIN number.

Faulty Receiver Module

The key fob houses an electronic receiver that sends the signals to lock and unlock. If the receiver module is damaged then all the on-board electronics will cease to function. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob itself may help.

This problem could be caused by a dead coin cell battery either from water damage or signal interference. You can reset the on-board computer if you disconnect the 12 volt batteries for about 15 minutes. This will drain any residual electricity that could be causing issues. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First positive, then negative the next.

Dirt and water can damage the internal chip of the key fob. If your key fob stops working after getting wet, wipe it with isopropyl, or an electronics cleaner. Then, you can reinstall the battery. If the key stops working after being exposed to soapy or salted water, it's likely that the chip has been damaged and must be replaced.

Another possibility is an inoperable antenna module fuse that is sending the lock or unlock signal to the vehicle. Depending on your model, the fuse is located in a variety of locations such as the engine bay, side of the dashboard, under the rear seat, or in the trunk.
