Dead Coin Battery
A dead battery on a coin is the most typical cause of a key fob that isn't locking or unlocking your car. Before it dies, you will see an increase in range or no power. It is easy to replace it with a fresh one (CR2025) from a local supermarket. Be aware that using the wrong or non-compatible batteries could damage your key fob. Be sure that the replacement battery is the same size and voltage, as well as the same specifications.
If your device has been exposed to clean water, for example rainwater or soapy water from the tap It is likely that corrosion has damaged the chip's electronic circuit. You could try cleaning the chip using isopropyl alcohol or an electronic cleaner to see if it helps but it is most likely that the chip has been fried.
A new key fob is the most straightforward solution. Major car dealers sell keys and can be installed by a seasoned mechanic. They can also be bought on ebay.

Water Damage
You might think that your key fob is destroyed if drop it into the water or accidentally wash it. But there's a way to salvage it. When the circuit board on the fob is exposed to water, it becomes an electrical conductor, which shorts the components. It also accelerates corrosion and rust.
Fortunately, this is easy to fix. Find something absorbent to place inside the fob. A tissue or paper towel would work. Use a cotton swab soaked in isopropyl to wash the circuit board and any other components. Let the fob air dry in a dry, warm environment for several weeks.
Once the fob is dried out, replace the battery with an alternative of the same size and the same polarity ('+' with the upwards direction). The fob can be difficult opening to access the battery, however when you have a flat head screwdriver on hand it will be a breeze to insert. After the fob is reassembled it should function as normal. If it doesn't work it may be necessary to program it again or replace the module.
Radio Interference
When a key fob functioning properly, it sends a radio frequency signal, which is received by the receiver module in your car. If the signal is disrupted the key fob will not function. seat ibiza key programming can be caused by objects such as weather conditions, objects, or other transmitters that operate at the same frequency as your car.
This could cause your key fob to not be able to activate the vehicle's systems for example, the ignition switch, or the security system. In this case, it would be best to replace the battery in your key fob.

If the issue persists after replacing the battery, the antenna of the key fob might be damaged or is malfunctioning. The antenna is responsible for transmitting a signal between the key fob and the receiver module. An OBDII scan can aid in diagnosing the issue by telling you exactly what's wrong with your system. The scanner will ask for details about the vehicle you own including the make and model, engine type, and VIN number.
Faulty Receiver Module
The key fob has a receiver module which transmits signals for locking and unlocking. If this module fails then all the on-board electronics will stop working. Reprogramming the key fob using an OBDII scan or replacing it may help.
This problem could be caused by a dead coin-cell either from water damage or signal interference. You can reset the onboard computer if you disconnect the 12 Volt batteries for 15 mins. This will remove any remaining electricity that could be causing problems. Begin by removing your cable from the negative terminal first, then the positive terminal. After 15 minutes, connect your battery in reverse order. Positive first, then negative, and finally negative.
The internal chip in the key fob can be damaged by dirt or water. If your key fob stopped working after getting wet, clean it using isopropyl or an electronic cleaner. After that, replace the battery. If your key has stopped working after exposure to soapy or salted water, it's likely that the chip has been fried and needs to be replaced.
A defective antenna module fuse could also be the cause. It is the fuse that transmits a signal to the vehicle to lock or unlock. Depending on your model the fuse can be located in one of the many locations including the engine bay, to the left of the dashboard, beneath the rear seat, or trunk.
