Access key

Wondering if anyone can help me figure out key number for a couple cars we just took over... pics below is of one of the hall switches we need to replace. It appears the in car switch and hall switches are the same... The switches are marked ACE on them as you can see... I have a set of universal inspection keys, tried them all and none worked... figured it was an ACE 6305 but that one didnt work either... Need to replace one of the hall switches however I have 2 cars here that both appear to be same keys so trying to figure out what other ACE keys might have been used for access in the past? Went to EPCO for some help but got nothing. appreciate any help

Do you know who made the fixtures? How about the controller? The ACE isn’t going to help much because it has nothing to do with the way the key is cut. The one in the picture has been turned half way and the key removed. Even to get the right key in there you’ll have to grind the nub off.

Epco 2?
