99 Toyota Land cruiser 100 USA version, customer lost the only key they had. Found some really old thread, post #12 stating Toyota will pay for a new ECM to program. Is this still available today?

Also from the same tread, Cruiserdan stating if you lose your keys that you would have to replace the ECM.

Virgin immobilizer chips available

I now have eeproms with the virgin immobilizer program written to them. I installed one in an extra ecu and was able to add keys to it and start my LX. It looks like this will be the cheapest way to virginize your ecu to accept keys. These work in my 1998 LX470 and I am pretty sure it is the...

Another option might be using a local (mobile) locksmith. It probably won’t be “cheap”, but probably cheaper than buying an ECU from the dealer.

Got some more information, customer had a locksmith come to his house, locksmith pulled the ECM took it with them and brought it back. When looking at Data stream there are no keys assigned, I'm assuming they replaced the eProm. Don't know why but they had pulled a bunch of fuses, some were burnt. Fuses have been checked and replaced. Thinking the locksmith they used didn't know about the missing and burnt fuses. Initially we had no communication and after replacing the fuses we have communication.
