My immobiliser is not working after ichanged batteries. Even after I replac?

Do you mean imobiliser or remote central locking?

If its the remote cenrtal locking it can usually be fixed by puting the key into the drivers door lock and operating the remote fob while the key is in the lock. The car will then 'sync' itself with the fob

You need to take it to dealer and get your key programmed to the ECU. 5 minute job
