Horn beeping with engine off

[rjw1]

Any Suggestions? I have 43' Dutchstar (2007) and with engine off, my horn has started to beep and the information keys start flashing. After several tries, I held down the 2 keys (up ^ and sideways) for about 10 seconds and horn stopped. This is the 3rd time the horn has gone off and it was 6 AM this morning....

Your keyless entry system is failing.

This is a common issue. Search for keypad issues and you will find a treasure trove of info.

I just had my Keyless Entry System worked on at International......it was beeping and is new system. Seems like that was fixed but did sound off over a few bumps. The horn beeping with engine off at stange times is problem.....I push down both in Light Message Center and then beeping stops and flashing. I think the last time I caught ASB error, don't know for sure.
Thanks! Thanks! Bob

Here's the new Essex keyless entry instructions and wiring. The wiring is all the same on the older ones. You might pull the key pad off and clip the alarm wire for a quick fix until you get it replaced. new pad is $179 from A1 Electric out in California.Old key remote will work with new one. Don't need to replace.
