My 2013 Mehran locks do not open with any other key. It is just 20970 kms driven and used rarely. About three weeks ago I locked out myself outside an ATM. Luckily I just had the phone with me so called Careem and went home and took out the spare key and came back.
This is just the second incident. First one was in March 2013 outside ETO Islamabad office when it was in F-8.Gave like 300 rupees for a mechanic to open the door and access the keys.
Now I try to always lock the driver door with key and not lock by lifting the door handle.
The feature I like in Grande that it does not lock if the key is inside. Only driver door is locked if you go by the conventional method of locking from door lock and then from outside pull the handle and shut the door, the driver door locks but rest of three doors remain open.
