Description
Set of locks – driver’s door, tank cap and switch box plus 2x keys
The key may not have remote control
buttons
Part description
This set of locks is intended for Citroën cars (according to the labels, mainly Citroën C2, Citroën C3 and Citroën C3 Pluriel) and solves the replacement of several key elements at once: the driver’s door lock, the fuel cap lock and the switch box. Also included are 2 plates/keys, so after assembly you can have all the listed locks combined into one set.
Suitable when a key is lost, the lock is damaged, the switch box is jammed or when you need to have the locks aligned without combining different keys. The key doesn’t have remote control buttons – this kit is primarily about the mechanical unlocking/switching part.

Installation recommendations
Generally/typically for changing a set of locks (exact steps may vary depending on the specific design of the car and locks):
1) Before assembly
- Compare with the old piece: the shape and design of the door lock, switch box and tank lid lock, type of attachment and connectors (if included in the assembly).
- Check the condition of the keys/plates: they are not significantly worn, cracked or bent.
- Verify compliance against codes 4162AH / 4162AG on the part/package if available.
2) Necessary tools and materials
- Basic set of screwdrivers and bits (Torx/hex depending on design)
- Plastic crowbar for removing upholstery/covers
- Pliers and small tools for fuses/clips
- Cleaning agent for degreasing and cloths
- Suitable lubricant for mechanical locks (typically graphite or for lock inserts)
3) Step-by-step assembly procedure
- Secure the vehicle against movement and prepare a work area.
- Disconnect the battery (recommended for work around the switch box and electrical parts).
- Remove the necessary covers/trimming (typically the door trim at the door lock and the covers around the steering column at the switch box) to access the fixings.
- For the door lock, loosen the locking insert and disconnect the rods/cables according to the design.
- Remove the old door lock insert and prepare the hole/saddle (clean dirt, check clips and seals).
- Replace the tank cap lock (depending on the version, release the lock and remove the lock, clean the contact surfaces, fit a new one).
- Remove the covers for the switch box and release the fixing of the box according to the design (work carefully so as not to damage the surrounding parts).
- Install the switch box from the kit and check for smooth operation in the key positions (without force).
- Install the driver’s door lock, connect the tie rods/cables and ensure proper seating and locking.
- Reinstall all removed covers/trims.
- Connect the battery.
- Test the function of all parts of the kit with one key (door, tank cap, switch box).
-
4) Post-assembly checks and test drive/function verification
- Verify that the key inserts and turns smoothly in all locks without binding.
- Check the correct function of the driver’s door lock/unlock and the mechanical function of the fuel cap lock.
- Verify that the switch box works in all positions and there is no spontaneous return/chop.
5) The most common assembly mistakes + how to avoid them
- Exchanging parts or not comparing the design → always compare the old and new part (fitting, shape, securing), ideally also according to codes 4162AH/4162AG.
- Damage to plastic clips and linings → use plastic pry bars and work gradually, without prying “by force”.
- Poor positioning of the pulls/cable at the door lock → before assembly, test the operation of the mechanism so that the lock does not remain in an intermediate position.
- Dry assembly without basic maintenance → clean the contact surfaces and use a suitable lock lubricant for mechanical parts.
Reasons why the part is damaged
- Wear of the planchet and lock inserts (long-term use, tumblers wear out)
- Clogging with dirt and insufficient lubrication (the lock begins to rub, the key becomes stiff)
- Freezing and corrosion of external locks (moisture, salt, weather)
- Violent damage when trying to break into the car or breaking the key
- Mechanical overload of the switch box (heavy set of keys, repeated “prying” when stuttering)
