Why doesn't the horn sound when locking the Excelle?

[McPaisley]

The reason why the horn does not sound when locking the Excelle is that the doors, trunk and hood are not properly closed, or there is signal interference, or it may be due to line garbling. In this case, it is necessary to go to a 4S shop for maintenance. The Excelle (Buick-Excelle) is the Buick Excelle, based on General Motors' global platform. The prototype of the Excelle is the latest global mid-size sedan developed by General Motors, designed and developed by General Motors Daewoo Auto & Technology (GMDAT).
