Ever wondered why some people get to leave the lab in a smooth unhindered fashion, whereas others always seem to get stuck at the glass door with the autolock?
As far as we can tell, much of this is cause by the sensitivity of the anti-tamper mechanism on the door lock. If it gets jogged or jiggled or bashed, it will assume you’re Made Of Evil, and it will lock up for several seconds. The same applies if you’re on the way in and you don’t wait for the latch to click open, or if the door has just slammed from the last person who went through.
The solution: always approach the door gently, and if it locks up, don’t HEAVE at it, just ease off and try again with a few soft pushes. After a couple of very gentle attempts to go through it will usually decide that you’re ok after all, and unlock for you.
