Welshguy is best to advise as he's had a couple of problems with his...

IIRC the technique is to push down on the lid as you press the button

It will be a tailgate lock failure - quite common on earlier cars - Click Here -

I believe it can be opened from inside with a screwdriver. See owners manual.

i ended up with a new lock and wiring loom under warranty, and as jacippit says you can open it with a screw driver from inside. pain in the bum to be honest

To open it in an emergency then

You need to drop the back seats and crawl into the boot to get at the lock and follow the instructions.

Got the same problem with my 05 SX petrol. Cost me £41 to be quoted £270 for a new tailgate loom (fitted). Seems exorbitant.

Tried to open from the inside but can't see the lock illustrated above. Do I need to remove anything to access it? Not technically minded at all!

Thanks in advance.

Welcome to C4Owners.org, Emma.

You should be able to open the boot from inside (means groping around with the seats down) with a suitable screw driver.

will try this tomorrow or though don't think it will work as I can't seem to remember if the bottom locking latch is exposed enough to get a screw driver in to it to be able to open it, will let you know shortly..

just glad I WAS GOING TO PUT THE DOG IN THE BOOT, and not the other way round before the boot decided to stay shut permanently...

The emergency unlocking latch isn't too difficult to get access to.

My first C4 had this problem, though I had wondered if carrying a very sandy retriever around in the boot helped much (as in covered in sand, not sandy coloured).

I have just had a similar issue with my coupe, but I found it was nothing to do with the lock or switch, Boot wouldn't open but dash displayed boot open message, which meant I couldn't arm the alarm or lock the car.
So I dismantled the entire boot lid and removed switch and lock, car still wouldn't lock only thing left was the wiper disconnected it and bingo car locked fine put it back together and switch and boot lock operated as normal.
2 hours later however my alarm started sounding I disarmed it but then the car wouldn't lock again accessed the boot through back seat removed panel and disconnected the wiper and all was/is fine since then I have just left the wiper unplugged and think I will remove the wiper altogether and use a grommet as the wiper does very little on a coupe anyway.
