keyless entry cancel

With a box van roll-up door, I need to cancel out the operation of the relays of an aftermarket power lock with a normally closed pin switch. Any suggestions are gold to me right now. Scraping the 30 hour investment is the only thing I've come up with.A day without learning or teaching is a day without value.

I didn't mention the pin switch is a ground at this point.A day without learning or teaching is a day without value.

What's the problem, the relays staying on?

Thanks for the interest, no everything works as they should. I just want to disable the locks when the door is open, via the pin switch. But with more contemplating, I've considered using a third relay in a starter kill set up to cut the 12v going to lock relay? Anything you can think of? Thanks, your humbled student A day without learning or teaching is a day without value.

Power to lock relays, use another relay:- Power for lock wires, cut one cut end to 87a, other cut to 30. Constant power, fused 2 amps to 86 Pin switch ground to 85 87 Don't use.

Thank you so much, I wasn't sure if that was the best way. A day without learning or teaching is a day without value.

I agree with Howie. Only question is, how long will this rollup door stay open? Any time the door is open, the relay will be energized, consuming a small amount of power. If the van's battery is in good order, and the door is open no more than a few hours, everything should be OK. If the van's battery is getting old, and the van is parked overnight (maybe in a workshop?) with the door open all night, the battery might possibly be dead by morning.

That's a good point Short of placing a switch in the 12v supply to the third relay, what else could I do? The door doesn't stay open all that much but I don't like things being "on" constantly eitherA day without learning or teaching is a day without value.

You could use a latching relay but they only switch 10 amps.
