7: Understanding Child Safety Locks
During the ’90s, cars were being designed with new child safety locks that would prevent the passenger doors from opening. A lot of drivers are still baffled by this and here is one such case that happened. “Mechanic Rebel_County recalls a customer coming to him, complaining that he couldn’t open the rear doors of his car. Sure enough, the doors would not open, and Rebel County was as baffled as to his customer. It finally occurred to him that… no, could it be something as simple as the child safety lock is on? And so it was. It was just too bad that this occurred to him only after he had pretty much taken the door apart.” – via Readers Digest.

For older cars especially those that were designed in the nineties the child safety lock is a manual switch. Thus, if this switch is engaged the doors will not open from the inside and it can create confusion for the consumer.
