What could be the issue for the cluster to not buzz to an open door?

The old owner has converted my Corrado from a G60 Auto to Manual. What could cause the instrument cluster to not buzz to a key in ignition, with a door open?

It sounds like the key warning switch inside the ignition key tumbler has gone bad, I would check all fuses and then switch the ignition lock out for a new unit. Check out the images (below). Please let us know what happens.

The old owner said he replaced the key cylinder. What wire enables the buzzer? Maybe it's the seat, because under the seat its disconnected, causing it to not buzz. My 06 Scion xB does this when the seatbelt buzzer is disconnected.

Yep, that could do it, can you connect the wiring under the driver seat to see if it fixed the problem?
