Anyone know where I can get a time lock from? I'm talking about the kind that you find used in safes that stay locked for so say 3 days or whatever and then release automatically and that cannot be overriden from outside once set.
I've looked on Ebay but nothing really fits the bill without having to buy the whole safe and I only want the lock. Any ideas?
Could one ask what sort of thing you are going to lock up for three days? IE is it a door, or something small? There used to be some electronic locks like this I seem to remember, and they failed safe if the battery went down, ie they opened, so yu did not have to use a drill to get them open!
I'm sure it was an american company, but further than that I cannot recall. Ideal for the kind kidnapper I thought.

The size isn't relevant, since I'm only after the lock mechanism.

Hi Another idea may be to buy a cheep 12v digital time clock (around £8) and use this to switch a 12v lock/solenoid/magnet etc. Can be cobbled using a small 12v SLA battery but bear in mind current drain otherwise battery will go flat. If mains operation is possible any small timer can be used or even an old central heating controller,only restraints would be size. Most electrical locks come as standard in both Fail secure (locked if no power) or fail safe (open on power fail). HTH CJ
