Dead Coin Battery
The most frequent reason for a key fob to not lock or unlock your car is a dead battery. It usually displays signs before it dies such as a decreased range or no power at any time. It is easy to replace it with a brand new (CR2025) one at your local grocery store. Be aware that using the wrong or unsuitable batteries can damage your key fob. Make sure the battery you replace has the same size and voltage, as well as the same specification.
If your fob has been exposed to clean water, for example rainwater or soapy water from the tap it is possible that corrosion has damaged the chip's electronic circuit. You could try cleaning the chip with isopropyl alcohol or an electronic cleaner to try to see if this helps but it is most likely that the chip has been fried.
A new key fob is the simplest solution. Most major car dealers offer them and they can be installed by a skilled mechanic. They can also be bought online from places like ebay.

Water Damage
You may think your key fob is damaged if you drop it in an unintentional pool or accidentally wash it. But there's a way to salvage it. When the circuit board inside the fob is exposed to water, it becomes a conductor that shorts out the components. It also speeds up the process of rust and corrosion.
Luckily, this is a simple issue to fix. Find something absorbent to place inside the fob. A tissue or paper towel would work. Use a cotton swab with isopropyl for cleaning the circuit board and any other components. Let the fob air dry in a warm, dry environment for several weeks.
After the fob has dried out and the battery is replaced with another one of the same size and the same polarity ('+' with the upwards direction). It can be tricky to open up the fob to get access to the battery, but if you have a small flat-head screwdriver handy it should slide in easily. After the fob is repaired, it should function like a normal. If it doesn't, then you'll have to reprogramme it or replace the receiver module.
Radio Interference
If a keyfob works properly, it sends out a radio frequency that is received by a module in your car. However, if the signal is distorted in some way the key fob won't perform as it should. This could be due factors like weather conditions, objects, or other transmitters operating in the same frequency range close to your vehicle.
In this instance it is recommended to replace the battery in your key fob. In this case, it would be best to replace the battery inside your key fob.
A few aftermarket LED lighting fixtures that uses the same frequency as a remote key fob might interfere with the signal, preventing it from reaching the receiver modules. The LED lighting must be turned off or switched to a different frequency in order to prevent interference.
If the issue is still present after replacing the battery, the antenna on your key fob may be damaged or not functioning properly. This is important because the antenna is responsible for sending signals from the key fob to the receiver module. Using an OBDII scanner can help diagnose this issue by revealing what's wrong with the system. The scanner will ask you for details about your vehicle, including the model, make and engine type as well as the VIN number.
Faulty Receiver Module
The key fob is equipped with a receiver module that transmits signals for locking and unlocking. If the receiver module develops a fault then all the on-board electronics will cease to function. If this happens it is possible to reprogramme the module using an OBDII scanner or replacing the key fob itself could help.
This problem can be caused by a dead battery in the coin-cell, water damage or signal interference. You can reset the onboard computer by disconnecting the 12 Volt batteries for 15 minutes. This will drain any residual electric current that could cause problems. Begin by removing seat ibiza key fob replacement from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, connect your battery in reverse order. First positive, then negative second.
The internal chip in the key fob can also be damaged by water or dirt. If your key quit working after getting wet, clean the electronic component with isopropyl Alcohol or an electronics cleaner before installing the battery. If it has stopped working after exposure to salty or soapy water the chip is likely damaged and should be replaced.
A faulty antenna module fuse could also be the reason. This is the fuse that sends an alert to the vehicle to lock or unlock. The fuse can be found in a variety of locations, based on the model. For instance it could be beneath the rear seat, or in the trunk, or the side of the dashboard.
