Just sorted the lock bounce problem. Display kept reading right front door open, the interior light didn't work (stayed on/flickered), audible key warning didn't work. Took lock out which is easy, prized the grey cover off, inside there's a black cover with two switches, prize that off, you'll see each switch has two prongs, these need bending back towards the contact strips. Clean up, reassemble, I used epoxy to glue back. Locks now work perfect.
