Help, please. I’m trying to restore/repair the buzzer/chime module system (for when the lights are left on, the door isn’t fully closed, the seat belt isn’t fastened, etc.).

While checking the ignition area, I found a broken piece that I think is part of that system. I’ve attached a photo. My guess is that it’s a sensor or switch that sends a signal based on the key’s position in the ignition, but I haven’t been able to identify the part number. It looks like it might be marked “F4TB”, but I still can’t find this piece anywhere online.



I’d really appreciate any information about what this part is (and the correct part number, if possible).

Thanks in advance—cheers!

 

That is the contact for the "key in ignition" warning buzzer
It fits just around the outside of the lock cylinder housing
Be careful with it, the little retaining tab breaks off pretty easily

 

Thank you very much for your response.
Unfortunately, the part is currently broken.
Do you know where I can get a replacement? The part number F4TB (see image) doesn’t return anything on Google.

 

See if this works for you.

How broke?
I've broken about a 30 of them over the years
I just use a small dab of clear silicone gasket / adhesive and stick them back on there
Once the ignition lock cylinder is back in place the key in ignition warning switch will also stay in place
A new one also comes with a turn signal switch
They never had them separate back then
It's pretty damn hard to run those wires down the column without pulling the whole switch out
