Spare keysRegain Entry Into Your Toyota
Lost, damaged or stolen your Toyota key? Right across the range — the Aygo, Yaris and Corolla, the RAV4, C-HR and Prius, the older Auris, and the Proace City and Proace vans — a modern Toyota key is not a cut-a-copy job. The car is immobilised, and it will not start on a key that has not been electronically coded to it.
Take the Toyota to a main dealer and you are usually looking at recovery to the branch, an appointment days away, and a bill that stacks the key, the coding and the transport. A high-street key cutter cannot rescue you either: newer Toyota smart keys use encrypted DST-AES (“H”) transponders that demand dealer-level seed-key authentication before a new key will programme. This is emphatically not a cheap copy — generic tooling simply will not talk to the car.
Lock City is a mobile auto locksmith that comes to you with the dealer-level software and the correct transponders for your exact Toyota. We cut the TOY43 or TOY48 blade on-site, handle the seed-key authentication the Smart Key System needs, and programme the key to your immobiliser at the roadside — no towing, no dealer wait, and every job guaranteed. Call 07967 097 899, Monday to Friday, 8am–5:30pm.
Toyota Key Systems Explained
Which Toyota you have decides the chip, the blade and whether a replacement is a quick spare or a full dealer-level job. Here is the honest breakdown.
Blade profiles: TOY43 and TOY48
- Older Toyotas (Aygo, earlier Yaris, Auris and Corolla) use the TOY43 blade; newer high-security models moved to the TOY48 blade [verify against your VIN].
- The first-generation Aygo (2005–2014) is a PSA-related car — built alongside the Peugeot 107 and Citroën C1 — so its key and immobiliser follow the PSA platform rather than mainstream Toyota.
Transponders: G-chip vs H-chip — the whole story
- G-chip (Texas DST80): the mid-era transponder, OBD-programmable with the right kit. Found on many pre-2015 Toyota keys.
- H-chip (Texas DST-AES, ~2015 onward): the encrypted smart-key chip. It needs dealer-level seed-key authentication before a new key can be added — a specialist job, not a cheap copy. The exact G-to-H cut-over depends on model and build date [verify against your VIN].
Smart Key System (keyless proximity)
- Toyota pioneered proximity keyless entry and push-button start on the Prius, and the Smart Key System is now common across the RAV4, C-HR, Corolla and higher Yaris trims.
- A smart key that suddenly is not detected is very often just a flat CR2032 fob battery, not a failed key — held against the start button it will normally still start the car.
All keys lost
- On smart-key (H-chip) Toyotas, all-keys-lost is the involved job: it takes dealer-level authentication and longer on-site than adding a spare, so keeping a programmed spare is far cheaper than being caught with none.
- The Proace and Proace City vans ride Stellantis (PSA) van platforms, so their keys follow that system rather than Toyota’s mainstream one [verify against your VIN].
Not sure which you have? Tell us your registration and we will confirm the exact chip, blade and whether it is a G or H key before we come out — and quote the real figure, with no guesswork.
What Our Customers Say
Excellent experience. Great communication, efficient timing, good price, accommodating & a very warm and friendly service. Would definitely recommend!
Great service today from Barry, the 4th locksmith/key technician to have a go at accessing my car after the keys were locked in the boot. Almost resigned to smashing the window, but he managed to access the car after 2 hours in the wind and rain, with a broken mechanism inside the lock, confirmed by the others who attempted the pick, brilliant stuff.
I was in a real panic, having locked my keys in my boot. Delighted with the efficient and effective service from this company. Had my keys back in my hand in under 5 minutes. Strongly recommend
Bought a new car which only had one key. These guys came out and created a second one quickly and inexpensively. Way cheaper than going to the main dealer and the only people in Bristol who could do it for the Audi A1 I have. Brilliant service.
Locked my keys in my car so Called at 9:45 and was out by 11. Very quick in my eyes considering it wasn’t a booked appointment. Came and unlocked my car in longer than 5 minutes!
Amazing service! I got an email response within minutes on a Sunday night. Arrived as arranged 8:30 next morning and had me back on the road within 30 mins for a very reasonable price. Highly recommended.
Brilliant service and at a reasonable cost highly recommended using this company.
