[Abid ABS]

Hi everyone I've lost my key for corolla hybrid and its cheaper to change all the ecus from another car from brakers yard £500 . Dealer wanted 2k any ways fitted everything except something called ecu id code box can't find it anywhere any one no location of it

Any one no ? Was told it could be behind the heater box that's a complete dash out can any one confirm this

New car, only one key? 

No record of key number? 

Tried the dealer?

I've got my replacement but trying to find the ecu id code box as seen in the picture above if anyone knows where it's hidden in the car would be great

I take it is a stolen recovered as you have no keys, you will need to program the vin and keys, the DCM will also give you issues unless you bypass it - if it is stolen its GPS and 5G trackable

Immobilizer code ecu - drivers side near the OBD 2 socket or in the steering column under the cowl

Lost keys that all dealer wants 2k so it's cheaper to buy a complete ecu kit witch I did comes with everything needed but the last box ecu id code A5 isn't anywhere to be found been told the complete dash will need to come out to get the heater box out it clips on the rear just wanted some confirmation before I remove everything

I very much doubt it's on the heater box, does the car have a keyed ignition or does it have the smart key ?
