door/key alarm does not work

@tus ,Tony, I did not find much at all on the net about test or replacing your trucks door chime, every thing was people wanting to get rid of chime/buzzer. I suggest you check all your fuses as a first step, check your manual may show a specific fuse for door chime although I did not find one. If all fuses look good next step would be to check and see if you have power going to the chime it self when door open(test light/DVOM). If you have power to the chime, then the chime assy. needs replaced. Below is a link to show where chime is located. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
