MESA = Avital Alarm Fob questions.

Looking to replace my key fobs as the plastic loop for the key ring is wearing out. One has already broken off.

Had the alarm system installed around 2018. Said MESA on the box and key fob. The key fob looks exactly like one from Avital.

MESA Model number is 7143M. Avital model is 7143L Anybody know if these will work?

In programming the new fobs it mentions using the valet button. I don't have one but it seems to be an easy install of a monetary switch. I can do that.

I suppose I could simply swap the internals into the new cases, but why not use the "new" electronics as well?

 

i'm not very good at counting. i would just swap the cases.

 

Yes it will work there identical besides branding mesa is a private label for special mesa dealers

 

Next question is, anyway to make these more robust? Certainly is a weak point in the design if you keep your keys in your pocket.

 

So, the new fobs came in and as the internals looked fine on the old ones I just swapped the old internals into the new case.

Thinking of the plastic loop on the fob this is a stress point between the plastic and steel key ring. So I tied a loop in a piece of 550 paracord and used that to join the two. Hopefully that takes care of it.
