The fifth-generation Ibiza, which has been revamped is a contender for the supermini segment. It goes toe-to-toe with the Renault Clio, Peugeot 208 and Ford Fiesta.


Use a small flat-head screwdriver or a thumbnail (A) to break open the battery compartment cover of the key fob (B). Replace the CR2025 coin battery by ensuring it is in the proper direction and polarity.

Dead Coin Battery

A dead battery for a coin is the most common reason of a key fob not locking or unlocking your car. It is likely to show signs before it dies such as a decreased range or no power at all. It is easy to replace it with a fresh one (CR2025) from a local store. Be aware that defective or defective batteries could cause damage to the key fob. Make sure that the new battery has identical in size, specifications and voltage as the old one.

If your device has been exposed to pure water, such as rainwater or soapy water from the tap, it is likely that corrosion has damaged the chip's electronic components. You could clean the chip with isopropyl or electronic cleaners to determine if that helps, but that the chip is fried.

A new key fob is a simple solution. They are available from most major car dealers and can be fitted by a professional mechanic. You can also buy them online, like on eBay. The best option is to work on a flat surface that has adequate lighting. This makes it easier to work on the tiny parts inside. You'll also be able to avoid putting something in the wrong place. Always work on your key fob in a location that is secure and safe.

Water Damage

You may think your key fob is lost if you drop it in a pool or accidentally wash it. However, there's still a chance. The issue begins when the circuit board in the fob is in contact with water. It creates a fantastic conductor and shorts out components. It also speeds up the process of corrosion and rust.

This is an easy solution. Find something absorbent, and place it inside the fob - a paper towl or tissue is ideal. Then you can use a cotton swab dipped in isopropyl alcohol to wipe down the circuit board and other components to clean out any battery acid residue and contamination. Let the circuit board dry for a few days in a dry and warm environment.

When the fob has been drained, replace the battery with a new one of the same size and the same polarity ('+' with the upwards direction). It isn't easy to open up the fob to reach the battery but if you have a small screwdriver that is flat that you have at hand, it will be able to insert easily. After the fob has been reassembled and working, it should operate just as normal. If it doesn't work, you'll require reprogramming it or replace the receiver module.

Radio Interference

When a keyfob operates properly, it sends out a radio signal that is absorbed by a receiver module in your car. However, if the signal is interrupted in some way the key fob will not function properly. This could be due to objects or weather conditions, or other transmitters that operate at the same frequency close to your vehicle.

This could cause your key fob's button to not work the vehicle's functions for example, the ignition switch, or the security system. In The KeyLab , it would be best to replace the battery in your key fob.

A few LED lighting products that uses the same frequencies as key fobs for remote control can interfere with the signal, preventing it from reaching receiver modules. The LED lighting must be turned off or switched to a different frequency in order to prevent interference.

If you have a new battery in your key fob, and the problem persists, it is likely that the key fob's antenna is damaged or malfunctioning. The antenna is responsible for transmitting signals between the key fob and the receiver module. Utilizing an OBDII scanner will aid in identifying the issue by revealing what's wrong with the system. The scanner will ask you for information about your vehicle including the make, model, engine type and VIN number.

Faulty Receiver Module

The key fob comes with a receiver module that transmits signals for locking and unlocking. All electronic components on board will cease functioning if this component develops a problem. Reprogramming the keyfob using an OBDII scan or replacing it may help.

This problem can be caused by a dead coin-cell battery, water damage or signal interference. It is possible to reset the 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 the cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.

Water or dirt can also cause damage to the internal chip of the key fob. If your key has stopped working when it was wet, wipe the electronic component with isopropyl Alcohol or an electronics cleaner before reinstalling the battery. If it stops working after exposure to soapy or salty water the chip could be damaged and needs to be replaced.

A faulty antenna module fuse could also be the cause. This is the fuse that transmits an alert to the vehicle to lock or unlock. The fuse may be located in a variety of places, based on the model. For example it could be located under the rear seat, or in the trunk, or on the side of the dashboard.
