If your Citroen C4 key fob isn't locking or unlocking the car, it might require an upgrade to the battery. This is a cheap and simple fix that can be done at home. First, make sure that the fob has been plugged into the wall and has power. Open the fob by using the small "key" that is built into the seam. Be careful not to damage the housing. Inside, you'll find a circuit board and a battery. The battery is a standard watch battery that can be bought at the majority of pharmacies and home improvement stores for a few dollars.

This method should work with most American automobiles. However, some manufacturers use proprietary technology that ensures only dealerships can create new keys, therefore it's best to inquire with your local dealer before attempting this at your home.

How do I program an alarm from a Citroen C4

There are many reasons why your car alarm may be going off. One possibility is that the key fob battery has gone flat which could cause the system to malfunction. Replace the battery and see whether that solves the issue. The alarm could also be triggered by external causes such as rain or wind. In this case you'll need to take the vehicle to a mechanic for a further inspection and diagnosis.

You can also check whether all doors are shut and the boot is shut. If not, you will be required to press button B on the remote control to secure your vehicle. You will know if the alarm is activated when you hear a siren, and the warning lamp 2 starts flashing. The siren will remain active for about 45 seconds. After the alarm has been activated, it can only be removed by entering the vehicle and turning on the ignition.

Another possibility is that the alarm is being triggered by external sources such as powerful winds or heavy rain. You can also try checking if the windows are shut, as even a small gap could cause the alarm to go off. If the issue persists, you should bring your Citroen C4 to a mechanic for additional examination and diagnostics.

Alarms could also be set off through electrical problems, such as malfunctioning wiring or sensors. These problems should be addressed immediately as they may lead to the theft of the vehicle. You can also try to stop the alarm from power by disconnecting the negative battery connectors from the battery. This will turn off the alarm, but it may also affect your vehicle's onboard computer as well as infotainment systems.

You may also try pressing the button on your key fob or if that doesn’t work, try putting the actual key into the door handle of the driver. This will stop the alarm, at a minimum temporarily, and should give you enough time to search for an alternative that is more durable.
