I called to SUZUKI Motors for the replacement of key and they had told me the F procedure.
1 Logged an FIR in the relevant Police Station where the car parked.
2 Then give the copy of that FIR to local SUZUKI dealers and they will forward it to SUZUKI Karachi.
3 After that an engineer will come with Branded SUZUKI's software and break the code which was punch at the time of assembling and install a new code and give you new key.
SUZUKI Motors will cost 8k for this job or reh gayi aap ki khawaari to us se un ko koi matlab nahi since they dont have any Customer Care Department.
