Recently I had to replace the ignition lock cylinder (with transponder keys) on my 2000 camry. Upon putting the new ignition lock in and turning the key, I found that the engine would crank but would not start. I believe this is because the new transponder keys are not programmed into the ECU, so the immobilizer will not disengage.

I have found several tutorials on programming a new key, but they all require the use of the old master key and the original ignition lock- my old key does not work with my new ignition lock.

The new ignition lock (for a 2000 camry) came with a new master transponder key, how do I set this up so that my car can start?

 

if no one answers in the next few hours ---a mobile locksmith may be an option

 

I actually contacted a locksmith earlier about the original broken ignition lock- I was told he might be able to fix it rather than getting a replacement. He wasn't 100% sure he could fix it and he would have charged me $25 just to come out and look at it.

Could the locksmith set up the key to work as a master key with the ECU?

 

yes with the correct scanner

it programs the modules and immobilizer ignition and recognizes the keys

double check the locksmith has the correct gear for a 2000 toyota
