I just bought a 1996 Renault Megane 1.6. The boot will not open via central locking or using the key. The central locking is a little bit iffy in general, if that is helpful.

It is a known issue on that vehicle. Strip out the lock, clean it of moisture, lubricate moving parts and seal it up with silicone.

Question edited for typos (magan) (stoped).

The fob needs to be reset. If this doesn't work, drop into a place that fits car alarms, or if you service at a dealership, they ought to do it for free.

Locking/Unlocking the doors from the outside
This is done using the RENAULT Card; see the "RENAULT Card" information in Section 1.
In certain cases, the RENAULT card may not work:
- if the RENAULT card battery is weak, flat, etc.
- if equipment operating on the same frequency as the card (mobile phones, etc.) is used;
- vehicle located in a high electromagnetic radiation zone.
It is then possible:
- to use the key integrated into the card to unlock the front left-hand door;
- to lock each of the doors manually;
- to use the interior door locking/unlocking control (refer to the following pages).
Using the key integrated in the RENAULT card
Insert key 1 into the lock in the driver's door and lock or unlock. Locking the doors manually
Turn screw 2 with the door open (using the end of the key) and close the door.
This means that the doors are then locked from the outside.
The doors may then only be opened from the inside or by using the key in the front left-hand door. Interior locking/unlocking door control
Switch 3 controls the doors, boot and, depending on the vehicle, the fuel filler flap simultaneously.
If a door or the tailgate is open or not closed properly, the doors and tailgate lock/unlock quickly.
If you need to transport objects with the boot open, the other opening elements can still be locked: with the engine stopped, press switch 3 for more than five seconds to lock the other opening elements.
Locking the doors without the RENAULT card
For example, in the event of a discharged battery or the RENAULT card temporarily not working, etc.
With the engine switched off and an opening element (door or boot) open, press and hold switch 3 for more than five seconds.
When the door is closed, all the doors and the tailgate will be locked.
Unlocking the vehicle from the outside is only possible with the RENAULT card in the vehicle's access zone or using the key integrated in the RENAULT card.
Door and tailgate status indicator
With the ignition on, the warning light integrated in switch 3 informs you of the locking status of the opening elements:
- indicator light on, the doors and tailgate are locked,
- indicator light off, the doors and tailgate are unlocked.
When you lock the doors, the indicator light remains lit and then goes out.

Most likley to be the micro switch in the boot quite common, u can open from inside if I remember correctly where the boot latch is in the centre the bit that keeps the boot closed on the left of the catch there is a little lever u can use a spike to open it , if it's not there there will be a little lever somewhere on the catch that opens the boot

It could be your onboard computer or locking module, as the guy next door had an identical problem on his Megane. A tech came and changed a module then programmed the 'brains'.
