The fifth-generation Ibiza that has been revamped, is a contender for the supermini segment. It competes against the Renault Clio, Peugeot 208 and Ford Fiesta.

Using a thumb nail or small screwdriver that has a flat head (A), prise upwards the key fob compartment cover (B). Replace the CR2025 coin battery, making sure it is placed in the proper direction and polarity.

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 vehicle. It usually shows warning signs prior to dying like a lower range or no power at all. It is simple to replace it with a new (CR2025) one from your local store. Be aware that defective or unsuitable batteries may damage the key fob. Make sure the battery you replace has the same size and voltage, and also the same specifications.

If your device has been exposed to clean water, like rainwater or soapy water from the tap It is probable that corrosion has caused damage to the chip's electronic circuit. You might try cleaning your chip with alcohol or an electronic cleaner to check if it works but it is likely the chip has been damaged and fried.

A new key fob is a simple solution. Most major car dealers offer them and they can be installed by a skilled mechanic. You can also purchase them online, like on eBay. The best option is to work on a flat, level surface with excellent lighting. This will make it easier to work on small parts inside. This also helps you to avoid putting something back into the wrong place. Always work on your key fob in a location that is safe and secure.

Water Damage

If your key fob gets soaked by dropping it in the pool or fumbling it in the wash, you may think that it's gone but there's hope. The problem is when the circuit board within the fob comes in 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 a simple issue to fix. Find something absorbent to place inside the fob. A tissue or paper towel would work well. Then, use a cotton swab dipped in isopropyl ethanol to wipe down the circuit board as well as other components to eliminate any residues of acid from batteries and contamination. Let  seat key  in a warm, dry environment for several weeks.

Replace the battery after the fob has dried out by a new one with the same size and polarity ('+' (pointing upwards). It is a challenge to open the fob to reach the battery but if you have a small screwdriver with a flat head at hand, it will slide in easily. Once the fob has been reassembled it should function like a normal. If it doesn't work, you'll need to reprogramme it or replace the receiver module.

Radio Interference

When a keyfob is working properly, it transmits a radio signal that is picked up by a receiver module inside your vehicle. If the signal is not received the key fob will not function. This may be due to things, weather conditions or other transmitters operating in the same frequency range near your car.

This could cause your key fob not to be able to trigger the vehicle's features such as the ignition switch, or the security system. It is best to replace your key fob's battery.

Some LED lighting from the aftermarket that utilizes the same frequency as a remote key fob could interfere with the signal and stop it from reaching the receiver modules. To avoid interference, the LED lights must be turned off or to an alternative frequency.

If the issue is still present after installing a new battery, the antenna of your key fob may be damaged or is malfunctioning. This is significant since the antenna is responsible for transmitting a signal from the key fob to the receiver module. An OBDII scanner can help diagnose this issue by telling you what is wrong with the system. The scanner will ask you to provide information about your vehicle, including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

The key fob has an encoder module that transmits the signals for lock and unlock. If this module fails and the on-board electronic components will stop functioning. Reprogramming the key fob using an OBDII scan, or replacing it might help.

This problem could be caused by a dead coin cell battery or water damage, or signal interference. You can reset your on-board computer by disconnecting the 12 volt batteries for 15 minutes. This will eliminate any remaining electrical energy that could be causing issues. Begin by removing your cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive and then negative second.

The presence of dirt or water could affect the internal chip inside the key fob. If your key fob stops working after getting wet, clean it with isopropyl or electronics cleaner. Then reinstall the battery. If it has stopped working after exposure to salty or soapy water the chip is likely fried and will need to be replaced.

Another possibility is a defective antenna module fuse that is sending the lock and unlock signal to the vehicle. The fuse can be found in several places, depending on the type of vehicle. For instance it could be under the rear seat or trunk, or on the side of the dashboard.
