Post 89 300 SE Horn Sounds When Key Turns In Door?

Hello, a guy put a new radio in my car and when I lock the car now the horn sounds! He swears it wasn't caused by him but it never did it prior. It's been a few months now and is getting old, having the horn honk every time I lock the car! Any suggestions please.
Also I have the old Becker radio that worked fine, should I hold onto it? I am thinking probally.
The car is flawless and runs perfect with 157K miles on it.

Audible Lock Settings....
He probably turned it on during the install. I'm not too sure about the 89, but all my previous cars had some sort of audible lock confirmation. And I know for a fact my new C has that setting in the dash, so i'm assuming its a switch or setting somewhere.

Yes the OEM radios carry a premium to many buyers. If you plan to keep your car in excellent condition then it would appeal to a collector or enthusiast who would value the Becker for originality and completeness, I sure would.
