loop detector question

[Jimmy Buffett]

I had a weird thing happen yesterday. My access door into the auto has had a bit of rust cancer for a while but no big deal. Yesterday something shifted that is making it VERY difficult to open and especially to close. As luck would have it it's really cold at night and after many days of snow we are really busy. I want to try to get through this rush before dealing with the door. I know that when the tech comes he can always get into the bay even if the doors are closed and I know that it has something to do with the loop detector. But that's all that I know. Can I just drive up close to the back door and it will open automatically?
Thanks
Jim

It probably is not the same with all brands of equipment. On my Mark VII door controls I can block the outside exit eye within one minute of it closing after a wash and it will reopen. After the one minute, blocking the eye does nothing. After you get the door open you need to install an "open" switch on the outside so you can get in if you need to (why don't you have a "man" door?). It would be very easy to do, even with your limited knowledge of electrical. I'm in the process of doing the same thing. I'm going to install a box with two buttons that will both have to be pushed at the same time to close the "open" circuit. I'm going to put the buttons on opposite sides of the box (and high up on the wall) so both hands will need to be used to depress them. This should eliminate unintended opening of the door by kids or whatever.

The man door is where my problem is. It won't open and close. I'll switch it out when it's not so cold and busy. I just need an alternative till then.

My back door does open if I pull up close to it.
