seat ibiza key fob for the Seat Ibiza The facelifted fifth generation Ibiza is an option in the competitive supermini segment. It competes with Renault Clio and Peugeot 208 as well as the Ford Fiesta. Use a small flat-head screwdriver or a thumbnail (A) to remove the battery compartment cover on the key fob (B). Replace the coin battery CR2025 and ensure it is in the proper direction and polarity. Dead Coin Battery The most common reason for a key fob that does not allow you to lock or unlock your car is a dead coin battery. It usually displays signs before it dies like a lower range or no power at any time. It is easy to replace with a brand new one (CR2025) from an area supermarket. It is important to be aware that using the wrong or incompatible batteries could damage your key fob. Make sure that the battery you purchase is the same size, specification and voltage as the previous one. 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 could try cleaning the chip with isopropyl Alcohol or an electronic cleaner to try to see if this helps but it is more likely that the chip has been fried. The simplest option is to buy a new key fob. Most major car dealers sell key fobs and they can be installed by a seasoned mechanic. They can also be bought on the internet through sites like ebay. It is best to work on a work surface that has good lighting. This will make it easier to work on the small parts inside. This will also allow you to avoid putting something back in the wrong place. Always work on the key fob in a secure and safe place. Water Damage If your fob's key gets soaked by dropping it in the pool or throwing it in the wash you might think it's over, but there's a chance. If the circuit board inside the fob is exposed to water, it develops conductor that shorts the components. It also increases corrosion and rust. This is a simple fix. Find something absorbent to place inside the fob. A tissue or paper towel will work well. Use a cotton swab that contains isopropyl for cleaning the circuit board and any other components. Let the fob air dry in a dry, warm environment for several weeks. Replace the battery once the fob has dried by replacing it with a new one that has the same size and the same polarity ('+' (pointing upwards). The fob isn't easy to open to get to the battery, but if you keep a flat-head screwdriver at hand, it should be easy to slide in. After the fob is reassembled it should function in a normal manner. If it fails you may need to re-program it or replace the module. Radio Interference If a key fob is functioning properly, it emits an audio frequency signal that is picked up by the receiver module in your car. However, if the signal is interrupted in some way the key fob will not perform as it should. This can be caused by objects such as weather conditions, objects, or other transmitters operating at the same frequency close to your car. This could cause your key fob's button to not work the vehicle's functions like the ignition switch or the security system. It is recommended to replace the battery on your key fob. Some aftermarket LED lighting that uses the same frequency as a remote key fob could interfere with the signal and stop it from reaching the receiver modules. To prevent interference, the LED light must be switched off or to an alternative frequency. If you've just replaced the battery in your key fob and the issue persists, it's possible that the key fob's antenna is damaged or malfunctioning. The antenna is responsible for transmitting a signal between the key fob and the receiver module. A scan of the OBDII can assist in diagnosing the issue by revealing what's wrong with the system. The scanner will ask you to provide information about your vehicle, including the model, make engine type, and VIN number. Faulty Receiver Module The key fob is equipped with the receiver module which transmits the signals for locking and unlock. If this module fails then all the on-board electronic components will stop functioning. If this happens Reprogramming using an OBDII scanner or replacing the key fob itself could aid. There are several possibilities for the cause of this problem such as a dead coin battery water damage or signal interference. It is possible to reset the on-board computer if you disconnect the 12 volt batteries for about 15 minutes. This will eliminate any remaining electric current that could cause problems. The cable should be removed first from the negative terminal, then from the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second. The presence of dirt or water could damage the internal chip of the key fob. If your key's function stopped after getting wet, you need to clean the electronic component with isopropyl ethanol or an electronics cleaner before installing the battery. If it stopped working after exposure to soapy or salty water the chip may be fried and will need to be replaced. Another possibility is a faulty antenna module fuse that is sending the signal to lock or unlock to the vehicle. The fuse could be found in various places, based on the type of vehicle. For instance it could be beneath the rear seat or trunk, or on the side of the dashboard.
