My
key warning buzzer as been working intermittently lately and I decided rather
than replacing it with another annoying buzzer unit I’d replace it with a
chime unit. Radio Shack sells a
small chime unit that fits into the same space as the buzzer.
The part number is 273-071 and should be in stock at your local store.
On
1971 cars like mine the key warning buzzer is located in the relay group that
is in the passenger foot well behind the glove box.
The cover on the relay group is held on with a wing nut.
Be sure to disconnect the battery before
removing the cover.
After
the cover is removed the buzzer unit can be removed.
It is held in place with a nut and has two wires connected to it.
The
mounting tab on the chime unit is too small to use with the original mounting
stud so I super glued a strip of ABS plastic on the bottom of the chime and
drilled a hole in the end of the strip to form a new mounting tab.
The
chime unit has three wires. I used
Radio Shack spade terminal #64-3038 and crimp the black and blue wires
together in one spade connector. The
red wire was crimped into a second spade connector.
The spade connectors insert into the original wires that were connected
to the buzzer unit. You may need to close the original connectors a little
with a pair of pliers so the connectors slide together snugly. The
black/blue chime connector goes to the green connector and the red chime
connector goes to the gray connector.
Before
mounting the chime I covered one half of the chime speaker with tape to reduce
the sound level.
After
the chime was mounted I replaced the relay group cover and connected the
battery. Play short chime video
sample. The chime has a pleasant sound that I prefer over the buzzer.
Update
Later
on I found a NOS buzzer on ebay for less than $30 with shipping. I
removed the chime and installed the buzzer. These are pretty costly from
the Pantera vendors.
