Toyota transponders and PIN codes.
OBD vs EEPROM bench read
Some keys can be added through the OBD port; all-keys-lost jobs can need a module reset or emulator procedure. OBD programming works through the diagnostic port; a bench read means removing a module and reading its memory chip (EEPROM) directly.
Toyota vs the dealership
A Toyota key without the dealer wait.
A dealer may need to order a key from UK and Japan and book the car into the workshop — sometimes meaning a tow if you have no working key. We come to your vehicle instead.
Where your model allows it, the key is cut, coded and tested at the roadside or on your driveway. If a step genuinely needs the dealer, we tell you on the call.

All keys lost
Some models need an extra procedure or module work to add a key when none remain.

FAQs
Toyota key questions
Do I need a Toyota dealer for a new key?
Not always. Many Toyota keys can be cut and programmed at your vehicle. We check your registration first; if your model needs a dealer-only step, we tell you on the call.
Can you program a Toyota key if I've lost them all?
Often, yes. All-keys-lost jobs can need the PIN or key data reading from a module. We confirm the method for your model before quoting.
Which Toyota models do you cover?
We regularly ask about the Aygo, Yaris, Corolla, C-HR, RAV4, Hilux. Compatibility depends on model year and key type, so we confirm it from your registration.
How much does a Toyota key cost?
It depends on the key type, model and whether any keys remain. We quote on the call before any work starts.
What do I need to show you?
Photo ID and proof that the vehicle is yours, such as the V5C logbook or finance or insurance documents.

Transit Custom Ignition Repair.
"I cannot recommend Alec enough. My transit custom lock was not turning. I did not know Alec at this point and called another locksmith. To cut a long story short the other locksmith attempted a repair and then gave up, leaving me with a van I could no longer use. I called Alec who came out next day; he repaired the damage done by the other locksmith and custom made a replacement ignition barrel so one key still does the doors and the new ignition. I couldn't be more pleased. Price was very fair too!"

"Did the work at a 3rd of the price of the dealership and I'm sure to a higher quality, the work was quick and professional. Could not recommend more!"
Can work on most cars! Pricing is very reasonable! Fast reliable service!
"Absolutely spot on! After ringing about 15 different companies who said they couldn't help and one company even saying the series of my car doesn't exist I found smarttech who I contacted who could finally help! The next day he came out and I now have access and a new key to my car! Fast and efficient polite service! Highly recommend!!"
