TriMark keyless entry system

[sidwinder]

Hello all i have a 2004 allegro bus with a TriMark key-less entry system. The two fobs work fine but the keypad does not work and i cant find the unit. Tiffin Tecks suggested first outside compartment behind carpeted door but just furnace there also the black grooved vent just inside the entry door but only a speaker in there any suggestions?

I had a 2005 Bus, but I've been told the location is similar to the 2004. I needed to pull the entire , vinyl-covered, lower dash panel in front of the passenger seat. Not easy but can be done.

Good luck
