If your key fob isn't responding to commands to lock or unlock it could require reprogramming. Several factors can cause this such as damage to the key fob buttons, moisture or corrosion in the battery contact terminals and mechanical problems in the circuit board.

Modern vehicle key fobs communicate with the car receiver using radio frequency technology. Each key fob has a unique identification code that is transmitted as an encrypted signal each time it sends a command to the vehicle. The car's receiver encrypts the signal, and then executes the action requested such as locking or starting the engine. When the new key fob is used, it must be programmed to work with the car's receiver.

In most cases, this involves entering a programming mode within the vehicle by turning the ignition key to the "on" position, and then returning to the "off" position within a specific time frame. The vehicle responds, usually by cycling the door locks or emitting the sound of a chime.

There are a variety of reasons your car alarm could be sounding off. The key fob's battery could be dead, causing your system to fail. Try replacing the battery to see if this resolves the issue. Another possibility is that the alarm may be triggered by environmental factors like rain or wind.

You can also try checking whether the windows are closed, as even a small gap could cause the alarm to go off. If the problem persists then you must take your Citroen C4 to a mechanic for additional examination and diagnostics.
There are electrical issues that could cause the alarm to go off, such as a faulty sensor or wiring. These issues must be fixed promptly since they could result in the theft of the vehicle. You can also try depriving the alarm off by disconnecting the negative connector of the battery from the battery. This will turn off your alarm, but may also affect the computer or infotainment system on the inside of your vehicle.
You may also try pressing the button on the key fob, or if that doesn’t work, you can try inserting the key that is physically in the door handle of the driver. This will temporarily shut down the alarm and give you time to find an effective solution.
