my boot hasn't locked for ages, unless you press it in, at the same time as pressing the key.. I thought I would take a look. the fault was the rubber stopper, behind the black cog..it had worn down.. I contacted Renault they wanted £50..you have to buy the full assembly ,not just the cogs and the motor unit.. i thought i would pop in local scrap yard, before going to Renault,the scrap yard had a clio 2002 in..it was on top of another car..and the boot was locked. i climbed up,got in the back,opened the boot, the car was rocking ha .i took the panel off,and took the motor cog thing off. bought it for a £1. i when home and fitted it,to my amazement it worked..
