Description
Luggage compartment lock right for PEUGEOT 307 CC cars
With functional microswitch 8484L4
Part description
This right boot lock is for the Peugeot 307 CC and comes with a working micro switch. It is a part that directly affects the correct closing/securing of the lid and at the same time the transmission of information about the state of the lock via a microswitch – important for the trouble-free operation of the car’s comfort and safety features.
When searching, it is often entered by part number, so we list all available designations: 9651004580, 8484L4, 8484Z3 (NFP).

Installation recommendations
Generally/typically for replacing a boot lock with a microswitch, the exact procedure may vary depending on the specific car design and type of attachment.
1) Before assembly
- Compare the new and original part: lock shape, mounting, microswitch connector/wiring and matching markings 9651004580 / 8484L4 / 8484Z3.
- Check the mechanical operation of the lock (no jamming) and the condition of the connector (no oxidation, damaged pins).
- Check that the part includes a functional microswitch (see description) and that it is not loose.
2) Necessary tools and materials
- A set of common hand tools (screwdrivers, ratchet/extensions according to the type of joints)
- Tool for removing plastic upholstery (upholstery levers)
- Electrical contact cleaner (as needed)
- Work light and protective gloves
3) Step-by-step assembly procedure
- Secure the vehicle against movement and provide access to the lid/boot.
- Disconnect the electrical circuit according to common practice for working on electrical parts (typically disconnecting the battery) to avoid a short circuit.
- Remove the lid inner trim/upholstery to gain access to the lock and microswitch connector.
- Disconnect the microswitch connector carefully (do not twist the cables, release the connector lock).
- Unfasten the lock and remove the lock.
- Check the lock contact and the surrounding mechanics (backlash, dirt, deformation), or clean the contact surfaces.
- Install the used lock in its original place and lightly seat it so that it can be fine-tuned if necessary.
- Connect the microswitch connector and check that it clicks properly and does not move.
- Tighten the lock attachment and verify that the lock did not twist while tightening.
- Before reinstalling the trim, perform a manual closing/unlocking check to verify smooth operation.
- Refit the lid trim/upholstery making sure no cables are pinched.
- Restore power (if disconnected) and perform functional test.
-
4) Post-assembly checks and test drive/function verification
- Check that the lid stays closed, that it does not unlock by itself, and that the lock does not make unusual noises during handling.
- Verify the function of the microswitch (typically a state change when opening/closing – depending on the car’s equipment).
- After a short ride, check again that everything is firmly attached and free of play.
5) The most common assembly mistakes + how to avoid them
- Pinched or pulled microswitch wiring – run cables in original routes and secure with clips.
- Unsnap connector – after connecting, gently pull on the connector (not the cable) to see if it holds.
- Poor seat of the lock – before final tightening, check that the lock sits straight and runs smoothly.
- Assembly without counter check – a damaged or misaligned counter can cause poor closing and faster wear of the lock.
Reasons why the part is damaged
- Normal mechanical wear of the locking mechanism due to frequent use.
- Intrusion of moisture and dirt into the mechanism – corrosion, stiffening of the movement, increased friction.
- Microswitch failure (contact fatigue, moisture, oxidation of the connector) leading to incorrect information about the state of the lock.
- Reckless handling (sudden banging of the lid) and subsequent damage to the internal parts of the lock.
