FInd out from a dealer if they put antitheft devices in the remote itself. If this is the case, find out if there is any way to deactivate the antitheft device.
I was in a shoe store, and going in there wasn't a problem, but when I left, I set both sets of doors off, it was loud, and people came running from everywhere. Scared the tar outta me.
The next time I went in, I stopped before I went in, and told them there was something in my purse that set the doors off. The manager says, oh yeah, I remember you. Sure enough, both doors again. I had some time to waste, so I stopped at the counter, and took my nook out, took my credit and debit cards out of it, ran it over the demagnitizer, then the same with my wallet. My wallet beeped a couple times on their demagnitizer, and finally cleared. Oddly enough, it never set my works alarms off.
