About OBD Port
This port provides connectivity to car's computer ECM required for finding and analysing faults in car. Key programming is also possible through this OBD port.
You can find this port near driver door. It is usually covered in a Black color plastic cap to protect it from dust & water so it may be hard to find. You need to remove this cap to reveal the OBD port.
When we first tried to find this OBD port, it was very hard to spot as it was concealed with a plastic cover. We were trying to find it under the dashboard but without any luck. After 1 hour, we were able to spot it attached to chassis near driver door.
We have found that thisis only available in those Maruti Suzuki Omni (Van) which has chip. You can use any good key coding device like to program a new key. Process is same as that of Maruti Alto, Zen Estillo or 800 (2007 to 2009 model)
Few Maruti Van even havechip which can't be programmed in similar way. You can either use some key cloning device like or to make a clone or special connector (usually available with Maruti Suzuki dealers) to make a duplicate key. If you are unable to find this port in the car then its definitely an ID 46 and can't be programmed in usual way.
