With a thumb nail, or a small flat head screwdriver (A) lift upwards the key fob battery compartment cover (B). Replace the CR2025 batteries, making sure it is inserted in the proper direction.
Dead Coin Battery
The most frequent reason for a key fob to not allow you to lock or unlock your car is a dead coin battery. After it has died, you will notice a decrease in range or no power. It is simple to replace with a brand new one (CR2025) from an area supermarket. You should be aware that using the wrong or unsuitable batteries can damage your key fob. Make sure the battery you replace is the same size and voltage and has the same specification.
If your device was exposed to clean water, such as rain or soapy tap water it is likely that the electronic chip inside has been damaged due to corrosion. You could try cleaning the chip with isopropyl Alcohol or an electronic cleaner to test if it helps, but it is likely the chip has been damaged and fried.
The simplest option is to buy an entirely new key fob. Major car dealers sell keys and can be installed by a skilled mechanic. You can also buy them online, for example on eBay. It is best to work on a work surface that has adequate lighting. It is easier to work with the smaller parts. This also helps you to avoid putting anything back in the wrong location.

Water Damage
If your fob's key gets soaked by dropping it in the pool or throwing it in the washing machine, you may think it's over, but there's a chance. The problem starts when the circuit board inside the fob comes into contact with water. It creates an excellent conductor, and it shorts out the components. It also speeds up the process of rust and corrosion.
Luckily, this is simple to fix. Simply find something absorbent and put it inside the fob - paper towl or tissue work well. Then, use the cotton swab, dipped in isopropyl alcohol and wipe down the circuit board and other components to get rid of any residue of battery acid and contamination. The fob should dry for some time in a dry and warm environment.
When the fob has dried out and the battery is replaced with a new one (of the same size and polarity ('+' that is pointing upwards). It is a challenge to open the fob to reach the battery, however if you have a small flat-head screwdriver available, it should be able to slide into easily. Once the fob has been put back together, it should work just as normal. If it doesn't, you may need to reprogramme it or replace the receiver module.
Radio Interference
If a key-fob is functioning properly, it sends a radio frequency signal that is interpreted by the receiver module in your car. If the signal is interrupted the key fob will not work. This can be caused by objects such as weather conditions, objects, or other transmitters that operate at the same frequency as your vehicle.
This could cause your key fob to not be able to activate the vehicle's functions, such as the ignition switch, or the security system. It is best to replace the battery on your key fob.
A few aftermarket LED lighting fixtures that uses the same frequency as the remote key fob may 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 to keep out interference.
If you have a new battery in your key fob, and the problem persists, it's possible that the antenna of your key fob is damaged or has stopped working. This is since the antenna is responsible for sending signals from the key fob to the receiver module. An OBDII scanner can assist in diagnosing the problem by revealing what's wrong with the system. The scanner will request details about your vehicle including the make and model along with the engine type and VIN number.
Faulty Receiver Module
The key fob contains the receiver module which transmits the signals to lock and unlock. If the receiver module fails that causes it to fail, the entire onboard electronics will stop working. If this is the case, reprogramming with an OBDII scanner or replacing the key fob may help.
There are a few possible causes for this issue that could be the cause, such as an empty coin battery, 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 power that could be causing problems. Start by removing seat ibiza car key replacement from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order first: positive, then negative second.
Dirt or water can cause damage to the internal chip of the key fob. If your key stopped working after it got wet, you need to clean the electronic component with isopropyl alcohol or an electronics cleaner before installing the battery. If it is not working after exposure to soapy or salty water the chip could be damaged and should be replaced.
Another possibility is a damaged antenna module fuse that sends the lock or unlock signal to the vehicle. The fuse can be located in a variety of places, based on the model. For example, it could be under the rear seat or trunk, or the side of the dashboard.
