We were called out earlier to a Mercedes with the keys locked in the boot.
We unlocked the boot without causing any damage by picking the boot lock as this is the only way into the boot because there is a bulkhead between the cabin and the boot.
Once the boot was open, we could not get it to stay closed, then the owner said the guy from the national rescue company had tried to short circuit something in the electronics to make the boot open.
That’s when the owner and our engineer realised why the boot would not close. The problem was that the boot has an electronic switch system and by shorting whatever the rescue guy shorted, he caused a fault on the electronic boot lock which is likely to cost a lot to repair.
Please bear in mind that if you have a Mercedes with keys locked in the boot, the safe way to recover the keys is to call a competent automotive locksmith who will pick the lock and open the boot safely without causing any damage
