this does not work for the motorola rival

I have a Sanyo phone with Sprint--the reserve battery does NOT work--the free 411 does, and believe it or not, so does the remote access. My son has a Miata, he gave me his clicker and drove the car two blocks away, and locked the doors. I used his clicker with my phone to open his doors. I've heard its not SUPPOSED to work, but it did for his car.

it works, but most of them only work on Nokias, like checking the serial number and activating the reserve battery.

this stuff is all false, see http://www.snopes.com/autos/techno/keyless.asp and other answers at snopes.com

I have the hybrid Sprint phone with the Nextel walkie-talkie. I tried *3370# and it doesn't work on my Motorola ic502. However, I've been using the free 411 for a couple of years now.

I saw a local news story some time back on the keyless entry remotes for cars. Basically, there are so many of them that they are starting to overlap. So, you could open two different cars with that same remote. The auto rep interviewed said it's being blown out of proportion and that it was very unlikely you would see two cars in the same state with overlapping remotes. The reporter than went outside and stood in front of two Ford Explorers and hit one remote. Both unlocked. Two cars in the same fleet, not just random cars in a parking lot. I was paranoid as can be for a while after that story came out.

"I'm just like you only shorter."

The free 411 does work. I have been using it for almost a year now. Of course you have to listen to some stupid ads first that pays for us to have it Free. But it's better then having to pay for it.

The battery reserve I have not tried, but someone told me on myspace that it did not work for them

 I found the following on a thread about the same email...:

and those FACTs explained.. with details..

+) Calling 112 on your cell phone will (in some parts of the world, primarily Europe) connect you to local emergency services, even if you are outside your provider's service area (i.e., even if you are not authorized to relay signals through the cell tower that handles your call), and many cell phones allow the user to place 112 calls even if the phone lacks a SIM card or its keypad is locked. However, the 112 number does not have (as is sometimes claimed) special properties that enable callers to use it in areas where all cellular signals are blocked (or otherwise unavailable).

+) Cars with remote keyless entry (RKE) systems cannot be unlocked by relaying a key fob transmitter signal via a cellular telephone. RKE systems and cell phones utilize different types of signals and transmit them at different frequencies. Relaying remote entry system signals via telephone might work if the signals were sound-based, but they're not. An RKE system transmits an encrypted data stream to a receiver inside the automobile via an RF (radio frequency) signal, a signal that can't be effectively relayed via cell phone. (In any event, RKE systems and cell phones typically operate on completely different frequencies; the former in the 300 MHz range and the latter in the 800 MHz range.). It's possible this method might work with cars that use something different than standard RKE systems, but it might not work with the vast majority of models.

+) The claim that pressing the sequence *3370# will unleash "hidden battery power" in a cell phone seems to be a misunderstanding of an option available on some brands of cell phone (such as Nokia) for Half Rate Codec, which provides about 30% more talk time on a battery charge at the expense of lower sound quality. However, this option is enabled by pressing the sequence *#4720# -- the sequence *3370# actually enables Enhanced Full Rate Codec, which provides better sound quality at the expense of shorter battery life.

+) Entering the sequence *#06# into a cell phone may display a 15-digit identification string, but that function only works with some types of cell phones, and the efficacy of reporting the ID number to a cellular service provider to head off unauthorized use of a lost or stolen phone is limited.

I don't care what you think of me. You're not even alive in my world.

I tried the serial number thing and it worked! Then I tried the battery power reserve and it didn't work but then I switched it to *#3370# and it looked like it was working but of course I am fully charged so I'll try again when my daughters battery goes dead(and it WILL go dead because she forgets to charge it all the time)! I also dialed the free 411 not sure how that will work it does say this is a free call but standard cell charges apply so you are still using your minutes! But I do hate paying for 411 I'd rather just use up a few minutes!

i tried the activate reserve power and the code to check the serial number, both didn't work for me, the phone just acted like i was trying to dial a number.
