What does shiftlock mean on a car

The shiftlock on a car is a gear locking device. Here are its main functions: 1. By locking the gear, it ensures no gear skipping or disengagement, guaranteeing driving safety. Shiftlock prevents transmission failure that may prevent gear movement - pressing it allows forced gear shifting. 2. Shiftlock also serves a function in parking lots where attendants require manual transmission cars not to use the handbrake, and automatic transmission cars to be placed in N (neutral) gear without the handbrake. This allows parking attendants to move vehicles when they might obstruct others' entry or exit.
