If you're comparing quotes across London, the actual time on site is one of the most under-explained parts of the process. Here's what a typical appointment looks like from start to finish.
The short answer: 1-2 hours
Most Scorpion X CAN BUS immobiliser fits take between one and two hours, done entirely at your home or workplace anywhere in London. The exact time depends on the vehicle's wiring layout and how accessible the CAN BUS connection point is behind the dashboard.
- Arrival & car check (5-10 mins) — we confirm the vehicle, check the wiring is as expected, and talk through where the unit will sit.
- Trim removal & access (15-20 mins) — the relevant dash or footwell trim is carefully removed to reach the CAN BUS wiring.
- Fitting the unit (30-50 mins) — the Scorpion X is wired in and hidden completely out of sight, with no visible box or LED.
- Testing & PIN setup (15-20 mins) — we test the immobiliser fires correctly, then walk you through setting and using your own PIN sequence.
- Trim refit & handover (10 mins) — everything is put back exactly as it was, with your Thatcham certificate handed over on the spot.
Booking a Scorpion S5 tracker alongside the immobiliser typically adds 20-30 minutes to the appointment, since the tracker also needs a GPS antenna position confirmed.
What can make it take longer
A handful of factors occasionally push a fit toward the two-hour mark: aftermarket alarms or trackers already wired in that need to be worked around, unusually tight dashboard access on some smaller models, or a vehicle with non-standard wiring from a previous repair. None of these are common, but our engineers carry the tools to handle them on the day rather than needing a second visit.
Fitting at London workplaces
A large share of our London bookings happen at the customer's workplace rather than home — particularly around Canary Wharf, the City and West End, where undercover parking gives us a dry, secure space to work while you're in meetings. Just confirm with building management that a visiting engineer is fine, and we'll do the rest.

Can I wait with the car while it's fitted?
Yes, most London customers do exactly that — you don't need to leave the vehicle with us or arrange separate transport.
Does fitting time vary by car make?
Slightly. Vehicles with more complex CAN BUS wiring, like some German makes, can take toward the upper end of the 1-2 hour window. We'll give you a realistic estimate when you book.
Can you fit it in a car park or workplace, not just at home?
Yes — we regularly fit at office car parks, including undercover ones in places like Canary Wharf, provided there's space to work safely.
