Hi there,

It is possible your battery voltage dropped to a low point while doing this update.

It is wise to a battery maintainer connected to the Battery while doing any updating or programming.

are you telling me that I need to try to jump start it. The lights are bright and functioning. The lock symbol on the left of the dash flashes. The fob key seems to still unlock doors but will not crank the vehicle.

Did your update work ok?

Does the battery still appear to be ok, bright headlights etc?

Sounds like the immobilizer is not recognizing your key.

Have you got another key to try?

The key has two functions, one is remote access, one is to allow vehicle start.

Are you able to disconnect the battery for 2 minutes and then retry?

I hope my advice has been of assistance to you.

Kind regards
