Dodge bypass moduals

Has anyone else had trouble with data by-pass moduals for Dodge/Chrs,  namely   CHDL-1 or -2 or -3 or -4 PK,  Have you noticed things like doors lock/unlocking intermitantly, trunk popping, doors locking when you hit the brake.  I've had 8 go down in the last few weeks.  Any one use units that "work" properly?

Thanks

ya, almost all that i have tryed to use, have been sent back , they can't remember the bypass codes, and lock users out and such.

I like the chrdaa moduels, only 1 bad one out of 20 so far.
