2020 Chevy Suburban Add Spare Key

Even on 2020 Chevrolet Suburbans equipped with a traditional physical ignition cylinder, having a duplicate key is critical. We duplicated a metal blade transponder key and matched a new remote fob to ensure full, reliable access and ignition operation.

Services Performed:

• Precision Key Cutting: Traced and cut the high-security metal key blade to exact factory specifications for smooth ignition turn.

• Transponder Chip Clone/Programming: Programmed the onboard immobilizer transponder chip to communicate with GM’s passlock security system for instant engine start.

• Remote Keyless Entry Pairing: Synced the keyless entry remote buttons to control lock, unlock, panic, and rear hatch functions.

• System Testing: Verified mechanical operation in both the door cylinder and ignition, as well as chip authorization and remote range.
