It is absolutely not possible to open car doors with a fob remote over a phone of any sort. The signal cannot be transmitted over a phone. This has been around and around the net in various forms, no reputable source has ever been able to duplicate.

There are many ways other ways to unlock vehicle doors remotely, mostly relying on in-car infotainment systems AFAIK.

Please explain to me then, how did my door unlock? Two adults and one teenager checked every door and hatch, everything was locked. I have a 2002 Yukon, I do not subscribe to On-Star. I have two sets of keys, mine, which were locked in the truck and my husbands that were with him 1.5 hrs away. Teenager does not have a set of keys since she does not have her license yet and no way of getting a set made without me. Granddaughters are 8 & 3. The only other explaination would be my recently deceased MIL unlocked the doors.

There is another explanation, perhaps your husband purchased on-star for you and thought it would be funny to play a trick on you. Perhaps the doors were not locked at all, just a bit stuck.

All I can tell you is the simple fact that an RF key fob cannot open a locked car door through phone service. I am an engineer with over 3 decades of experience building electronics of many types including RF equipment. Believe me or not, perhaps check snopes.com (which will back me up), skeptics exchange (also backs me up) as well as 100's of other sites from key fob manufacturers and others. Or you can believe the sites that "publish" urban legends and myths without any facts to back up their claims.
