@Lisajet_SJC, I/m sorry you had to learn this lesson the scary way. But its a common and well known risk leaving a fob and your cell phone near each other. Men must carry the fob in one front pocket and the phone a different one. Cell phone signals will interfere to the point of cancelling out the fob's signal to the car. This warning has been stated many times on TMC.
When your are locked out of your S/X and the handles will not present, go to the trunk and try opening it. Sometimes even when the door handles will not present, the trunk is unlocked and will open. I can't explain the logic, but we know it works - sometimes.
For anyone else finding yourself like this, you have options. Don't paint yourself into a corner. If you can borrow another cell phone, ask if you can install the app temporarily, unlocked your car, delete the app. If you can get to a regular phone, call someone you trust, ask them to download the app, give them your password, unlock your car. Then when you get home, change your password. You are seldom "stuck in the mud", think - calm down, think.
I've said this many times on TMC. Find one of your old phones, turn on WiFi, add the app, login and leave it in your garage. Leave it next door in a friend's garage. Buy a $20 burner phone with WiFi, put it in your neighbor's garage. Think. What if your SA had not been at work. What was your next step?
This had nothing to do with the MCU. Reading "catchy - attention getting titled" threads on TMC is an investment, not just killing time.
