Losing your only car key can turn a simple errand into a major headache. That’s exactly what happened to a Subaru Ascent owner in Etobicoke who contacted Direct Locksmith Toronto on a Sunday evening after his SUV displayed “Key Not Detected.”
1️⃣ Emergency Call-In
At 8:35 p.m., our mobile locksmith team arrived at a grocery store parking lot where the client’s 2022 Subaru Ascent was parked nose-in between cars, making towing impossible. He had lost his only proximity fob and needed an on-site key replacement to get home safely with his family.
2️⃣ Initial Assessment
- Working keys: None (all keys lost)
- Vehicle battery: Stable voltage, recently tested
- Dashboard: “Key not detected” message only
We confirmed it was an all keys lost situation on a Subaru proximity system. The plan: verify ownership, enter service mode, program a new OEM smart fob, delete the missing fob for security, and cut a new emergency key blade.
3️⃣ On-Site Diagnostics
After verifying ownership (registration, licence, VIN), we connected a Subaru-compatible diagnostic tool to the vehicle’s OBD-II port.
We:
- Confirmed immobilizer lockout and available key slots
- Performed an RF sweep to ensure the lost key wasn’t nearby
- Checked 12V battery and network stability for safe programming
4️⃣ Programming Process
Using authorized access, we entered the Body Control Module (BCM) service routine and prepared a factory-grade OEM smart key compatible with the 2022 Subaru Ascent.
Steps included:
- Programming the new proximity fob to the immobilizer system
- Deleting the missing key’s data for security
- Laser-cutting and fitting the emergency override key
- Testing remote lock/unlock, push-start, and liftgate release
- Running a final scan to ensure all systems were clear
5️⃣ Testing & Verification
We tested the new smart key across all functions:
- Lock/unlock and push-start (10 cycles)
- Passive entry on driver and passenger doors
- Panic button and liftgate release
✅ Everything worked flawlessly.
We also advised the customer to replace the CR2032 coin cell battery every 18–24 months and store spare keys away from wireless chargers or strong RF signals.
6️⃣ Completion & Warranty
Total time on-site: around 50 minutes. No towing was required. The client received a fully programmed OEM Subaru smart fob plus a cut emergency blade, and the lost fob was securely removed from memory.
