Problems with Car Keys

I recently rented a car from one of the large car rental companies. It was a late model, mid-size auto with the usual keyless electronic door lock system. Inside, instead of the traditional key activated ignition, there was a button that you press to start the engine. I drove to my hotel, got out of the car and tried to lock all the doors with the key fob. The doors would not lock. I tried to lock them manually, but when one door locked, another unlocked. Finally, I called the 800 number for customer support and was advised that there was a fault in the system and that I’d have to return the car to the rental place and get a different vehicle, which is what I did. The real problem was that since the ignition was activated by a button, and not with a key, anyone could have climbed into the driver’s seat, started the car and driven away. 

I admit, I’m not a big fan of electronic gizmos, and this is part of the reason. Why would a car designer not include some sort of manual override to insure that the vehicle is secure when the owner (or renter in my case)  is away? In future, I’ll ask for a rental car with a standard keyed ignition. At least I’ll have improved the odds in my favor a little bit of not coming back to an empty parking space where my rental ought to be.
