Here is my story I lost a key foe a 99 Echo, took the spare down to Toyota handed them the key they ordered a replacement $60. I pick up the replacement go get it cut $20. Take it back to Toyota to get it programmed. Then they tell me I have a sub key and you cannot program a new key from it. Sounds a bit suspect to me. They tell me $2500 to change the whole security system. My question is can I get a key programmed off a sub key? If so where? If not is the a way to turn off the immobilizer so I don’t need the security key?
