K12 2005 160sr boot will not unlock.

[Lovemy160srtobits]

Hello, found that my boot would not unlock today.

Played around pressing buttons etc, now and again it would open/allow me to lock it. Seems to sometimes work when I put the key in the ignition, but doesn't always work.

How do I diagnose the problem please, ie what are steps and order I need to check?

So no issues at all until today. Now and again it will work. Most of time it doesn't, and when I press the key to unlock it doesn't make the clicking noise. It does, when it works occasionally. Works once every 15 or so attempts. .

Thanks.

If it is just your boot, I would look at the condition of the wires that go from the body to the boot/hatch - they wear out over time due to the opening and closing motion. They are in a rubber sleeve, and wrapped in very sticky tape. It may be that the boot release wire has broken - I had a similar trouble with the rear wash, and wipers, so I ended up replacing *all* the wires, but if it is just the one you can possibly mend the broken wire.

If it's the central locking, that's a different story. Maybe also check/change the battery in your key?

Good luck

Most likely this, on mine 3 wires were 'worn cut', inside of rubber elbow.
Worked for awhile randomly, then stopped totally.
German eBay has available repair kit, 4 silicone wires and 8 heat shrink butt connectors.

Thanks for your replys. Sorted. Was the touch switch. Boot would unlock and lock just once, if I locked up car, opened it up and turned ignition on. Would have to go through that process for each unlock, and then again for a locking. Bought the switch and the lock off ebay, as was only £24 for both (new parts). Lock contains a solenoid with electrical connectors, so thought may as well change that at same time. Happy days. Phew.

Some parts are so cheap for micras now, people desperate to sell things off. 12 orange light bulbs for indicators, only £5. Lovely orange indicators now, the mot tester cannot have any complaints about yellow ones now.

I still enjoy my car so much. It's in great condition. Dread the day it gives up and dies.
