When you lose the only key to your truck, getting back on the road fast is critical. That’s exactly what happened when a contractor in Scarborough called Direct Locksmith Toronto early on a Monday morning. His 2021 Chevrolet Colorado wouldn’t start after the key went missing during a delivery run. He needed a new key cut and programmed on-site, the same day.
Step 1: Assessing the Situation
- The customer had no working keys left.
- The truck battery was healthy, but the dash showed the theft-deterrent light.
- This was an all keys lost situation, meaning we needed to program a new GM remote head key with both transponder and remote functions.
Step 2: On-Site Diagnostics
Our locksmith arrived on site and:
- Connected a GM capable diagnostic tool to confirm no active keys were programmed.
- Verified ownership with the customer’s registration, licence, and VIN.
- Confirmed no stray RF signals were interfering with the system.
Step 3: Cutting & Programming the New Key
- Decoded the door lock to retrieve the mechanical key code and confirmed against VIN records.
- Cut a precision HU100-profile blade on our laser machine and tested it in both the door and ignition.
- Prepared an OEM-spec GM remote head key compatible with the 2021 Chevrolet Colorado.
- Performed the immobilizer fast learn procedure, successfully pairing the new key and remote functions (lock, unlock, and remote start where equipped).
Step 4: Quality Control
Before handing the key over, we:
- Tested lock, unlock, and ignition multiple times.
- Confirmed remote features worked properly.
- Verified mechanical override worked smoothly.
We also advised the customer on best practices:
- Keep a spare key stored separately.
- Replace the coin-cell battery every 18–24 months.
- Avoid exposing the fob to moisture or strong RF signals.
Step 5: Results & Warranty
In just 45 minutes on site, the customer had a fully programmed GM remote head key with a cut blade. No tow, no dealership delays, and no wasted crew time. We issued a 3 months warranty on parts and labor.
