Summary

Keys that won’t come out of the ignition in 2021 Chevrolet Colorado trucks typically indicate park switch failure in the automatic transmission gear selector. Gateway Auto’s ASE-certified technicians diagnosed the intermittent key removal problem and discovered the park switch was failing to properly signal when the vehicle was in Park. Replacing the entire gear selector control assembly with a factory GM component restored reliable key removal function.

At Gateway Auto, we recently repaired this ignition issue on a Colorado ZR2. Here’s how we found and fixed it.

A: Yes, but you may get stuck unable to remove your key, which is inconvenient and potentially unsafe.

Q: Why replace the entire shifter assembly?
A: The park switch is integrated into the assembly and cannot be serviced separately.
