Dead Coin Battery

The most frequent reason for a key fob that does not be able to lock or unlock your car is due to a dead coin battery. It will usually show symptoms before it dies like a lower range or no power at all. It is easy to replace it with a brand new (CR2025) one at your local grocery store. Be aware that faulty or defective batteries could cause damage to the key fob. Make sure the battery you replace has the same size and voltage and that it is the same specification.

If your fob was exposed to clean water like rain or soapy tap water, it is possible that the electronic chip inside has been damaged due to corrosion. You can clean the chip with isopropyl or electronic cleaners to see if that helps, but the chip is fried.

The most straightforward solution is to purchase a new key fob. They are available at most major car dealers and can be installed by a qualified mechanic.

Water Damage

You may think your key fob is ruined if you drop it into a pool or accidentally wash it. But there's a way to salvage it. The problem is when the circuit board within the fob is in contact with water - it creates a fantastic conductor and cuts off components. It also accelerates corrosion and rust.

Luckily, this is simple to fix. Simply locate something absorbent and put it inside the fob. A paper towl or tissue work well. Make use of a cotton swab and isopropyl to clean the circuit board, as well as any other components. Allow the board to dry for a few days in a warm and dry environment.

Once the fob is dried out it is time to replace the battery a new one (of the same size and the same polarity ('+' that is pointing upwards). The fob can be difficult to open in order to access the battery, but should you have a flat-head screwdriver at hand, it should be easy to slide in. After the fob is reassembled and working, it should operate as usual. If it doesn't, you may need to reprogram it or replace the receiver module.

Radio Interference

When a key fob working correctly, it sends an audio frequency signal that is received by the receiver module inside your car. If the signal is interrupted the key fob will not work. This could be due to weather conditions, objects or other transmitters operating in the same frequency range near your seat car keys.

In this instance it is recommended to replace the battery in your key fob. In this scenario it's best to replace the battery on your key fob.

Some LED lighting accessories that uses the same frequencies as key fobs for remote control may interfere with the signal, preventing it from reaching receiver modules. The LED lighting must be turned off or switched to a different frequency to avoid interference.

If the problem persists after replacing the battery, the antenna on your key seat fob could be damaged or inoperable. The antenna is responsible to transmit a signal between the key fob and the receiver module. An OBDII scan will help you identify the issue by telling you exactly what's wrong with your system. The scanner will ask you for information about your specific vehicle, such as the make and model, engine type, and VIN number.

Faulty Receiver Module

The key fob has a receiver module that sends signals for locking and unlocking. All on-board electronic components will stop working if the receiver module is affected by a malfunction. If this is the case, reprogramming with an OBDII scanner or replacing the key fob itself may aid.

You can reset your on-board computer by disconnecting the 12 Volt batteries for 15 mins. This will drain any remaining power that could be causing problems. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect your battery in reverse order. Positive first, then negative second.

Water or dirt can also affect the internal chip inside the key fob. If your key has stopped working after getting wet, wash the electronic component with isopropyl Alcohol or an electronics cleaner before reinstalling the battery. If it stopped working after exposure to salty or soapy water, the chip is probably damaged and must be replaced.

Another possibility is a damaged antenna module fuse that transmits the lock / unlock signal to the vehicle. Depending on the model the fuse could be located in a variety of places like the engine bay, on the side of the dashboard, beneath the rear seat ibiza key fob, or in the trunk.
