disable Grandis immobilizer
 

Does anyone know how to disable immobiliser of 2010 Grandis? I recently had a battery replacement and before that, immobiliser was disabled. After the replacement, I believe immobilizer got enabled. Now, I can't leave the grandis open for even a few minutes as alarm automatically activates and when I open the door, alarm sounds. The only way to stop the alarm is to switch the engine on and press unlock in the remote key. Appreciate any advise.
