Duct tape and a spare key will work too

^ like most people do and myself. Key replacement for new outfits can run from 250 to 600$ I have been told. You just can't go the hardware store and have one carved out. So many people aren't hiding a spare because of the cost of a smart key etc.. What I have been told I haven't priced anything like that lately.

I don't need a smart key and I do not even use the power locks....all that stuff should be done away with, back to crank windows.

Not really, I keep a spare in my wallet and my wallet is never kept in my truck locked or unlocked.

Friend of mine keeps a key in a small box in a heavy duty ziplock bag zip tied to his frame..it’s a key with the chip..After he locked his keys in while hunting out of state he said he learned his lesson..
I need to do the same..

Sounds like the perfect app for car thieves.

^^^ Yup, I was just thinking the same thing.... all this technology makes it easier to rip people off.
I'm glad my Wrangler is a 1990, and my Country Squire an '86... although neither vehicle is considered old to me.
Now my 79 C-10 truck, and my 71 Plymouth... those are old !!

If you get a Tesla you can do it. You can also becon you car to come to you. So if you have to park far from a restaurant, eat to much, and don’t want to walk all the way to your car then you can get on the app and becon your car to come to you. Then take a nap with your hands on the wheel while your car drives you home. And once you get home, you can press the dance button and dance with your car in celebration. And that is all 100% true. I had a buddy do it haha.

Snowy, I hold my phone screen towards the driver side window. The person on the other phone pushes the unlock button aiming the fob into the voice microphone. I hope this works for you. I do keep a magnetic key box with a spare key on the truck also.

lestan101 >>> thanks. I will give it a try again and follow your steps. We basically did the same as you described but will give it a try sometime.

Yes, I have them wired on every outfit also. I had a friend that just bought a truck and hadn't got time to do that yet. He tried to do unlock with his wife at home and each had a cell but no go.

I tried this a few years ago when I got a new Dodge Ram and thought it worked, then I realized the range of my new fob was much greater than I expected and the phone had nothing to do with locking/unlocking the truck doors. The point being that, if you run a test, you need to be well out of fob range before coming to any conclusions that you might depend on in the future.

unless dodge is using some sort of sound based system - it simply can't work.

most wireless key fobs work on an radio frequency which can't be transmitted by cell phone.

Yep, it does work. My wife stood by the pickup door. I was about 10' away. I held my phone up, pushed the button, and wahlah....door unlocked.

Key just to open doors cost ~$3 to cut at Walmart, you don't need the chip in it and that is what costs. It wont start the car but it will unlock the doors and steering wheel.

I agree with l1ranger regarding using cell phones to transmit a signal from a remote fob. Like someone else said, the microphone and speaker in the cell is for sound and not radio frequency. That does not mean a cell phone can't be used to open the vehicle door. A cell phone signal is a radio frequency signal which it can both receive and transmit. So a cell phone can transmit a signal that matches the signal the fob transmits to open the door, start the vehicle, etc. That is just programming a cell to function as a fob and is not at all the same as transmitting a radio frequency signal through the phone speaker.

some of them fobs work from about a block away, but as said the sound transmitted through a microphone changed to RF then bounced to a tower and back to another phone and changed from RF to sound waves won't trigger the computer. It should be possible to program a phone to use the same rolling code frequencies as in a fob, but it might be as costly as buying a new car. Different frequencies and different coding technology and other stuff. A door bell might open your car door if connected to the right transmitter.
