This refreshed fifth-generation Ibiza is a contender in the crowded supermini segment. It is competing with the Renault Clio and Peugeot 208 as well as the Ford Fiesta.

Utilizing a thumb nail or small screwdriver with a flat head (A), prise upwards the key fob compartment cover (B). Replace the CR2025 battery and ensure that it is installed in the correct direction.

Dead Coin Battery

A dead battery for a coin is the most frequent cause of a key fob not locking or unlocking your car. It will usually show signs before it dies like a decrease in range or no power at all. It is simple to replace it with a new (CR2025) one from your local store. Be aware that faulty or defective batteries could cause damage to the key fob. Be sure that the replacement battery is the same size and voltage, and also the same specification.

If your fob was exposed to clean water, such as rainwater or soapy tap water it is possible that corrosion has caused damage to the electronic chip. You could clean the chip with isopropyl or electronic cleaners to determine if that aids, but the chip is fried.

The most efficient solution is to purchase a new key fob. The majority of major car dealers sell keys and can be installed by an experienced mechanic. You can also buy them on the internet, for instance on eBay. The best way to work is to work on a level surface with excellent lighting. This makes it easier to work on the tiny parts inside. This will also help you to avoid placing anything back in the wrong spot. Always keep the key fob in a secure and safe space.

Water Damage

You may think that your key fob is damaged if you drop it in the water or accidentally wash it. But there's still hope. If the circuit board inside the fob is exposed to water, it develops a conductor which shorts the components. It also accelerates the process of rust and corrosion.

Fortunately, this is not difficult to fix. Simply locate something absorbent and put it inside the fob - paper towl or tissue works well. Make use of a cotton swab and isopropyl to wash the circuit board, and any other components. Let the fob dry out for several days in a warm and dry environment.

Replace the battery when the fob is dry with a new one with the same dimensions and the same polarity ('+' (pointing upwards). The fob might be difficult to open to access the battery, but should you have a flat-head screwdriver it will be a breeze to slide in. Once the fob is assembled, it should work as normal. If it doesn't work, you may have to re-program it or replace the module.

Radio Interference

If a keyfob works properly, it transmits the radio frequency which is received by a module in your car. If the signal is disrupted the key fob won't function. This could be due to objects or weather conditions, or other transmitters that operate on the same frequency in close proximity to your car.

This could cause your key fob to not be able to activate the vehicle's systems like the ignition switch or the security system. It is recommended to replace your key fob's battery.

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

If the issue continues to persist after installing a new battery, the antenna of your key fob may be damaged or inoperable. The antenna is responsible to transmit a signal between the key fob and the receiver module. Utilizing an OBDII scanner will help diagnose this issue by telling you what is wrong with the system. The scanner will ask you for information about your vehicle including the make, model engine type, VIN number.

Faulty Receiver Module

The key fob has an electronic receiver that sends the signals for locking and unlock. If this module fails then all the on-board electronics will cease to function. If this is the case then reprogramming the module using an OBDII scanner or replacing the key fob itself could help.

This problem could be caused by a dead coin-cell battery, water damage or signal interference. You can reset the on-board computer by disconnecting the 12 Volt batteries for 15 minutes. This will draw out any remaining electricity that could be causing issues. Start by removing the 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, then negative, and finally negative.

The internal chip of the key fob can be damaged by water or dirt. If the key fob you purchased stopped working after being soaked, clean it with isopropyl, or an electronics cleaner. Then, reinstall the battery. If it is not working after exposure to salty or soapy water the chip is likely fried and will need to be replaced.

A defective fuse for the antenna module could also be the cause. This is the fuse that transmits an indication to the vehicle to lock or unlock. The fuse could be found in a variety of places, based on the type of vehicle. For example it could be under the rear seat alhambra key Programming, or in the trunk, or the side of the dashboard.
