Hi, Ford Focus 2006 hatchback.
I have the usual "Key Fob only sometimes unlocks the car" thing, which I understand is probably bad connections in the driver's door lock. I'm not really bovvered by this as I can always get in with the key, and stop the resulting dashboard bleeping by turning on the ignition. Maybe I'll fix this one day. The boot always unlocks via fob, and I can always double lock the car with fob. (If the unlocking fails and I get in mechanically, the dashboard alarm sounds, and the fob's unlock doesn't always kill the dashboard alarm, so it may just be a fob switch prob)
But the other thing is that the boot will randomly unlock whilst I am driving. It's done this several times now, one time going through perhaps 8 instances of the solenoid clicking away.
Today it did it on the M25, heading north at the north exit of the Dartford Tunnel with a load of stuff inside and nowhere to stop - a bit scary imagining all my stuff pouring onto a heavily congested carriageway. So now I realise this isn't a trivial problem.
It seems the boot lock (hatchback) is a two stage device like the bonnet? i.e. it can unlock to one level, but needs a second unlock to fully open? I say this because when I eventually was able to stop on the hard shoulder, I couldn't open the partially released boot, (keys still in ignition) but could push it fully shut.
Cheers,
Gareth.
