I m sorry to hear about ur issue ,we kind limited to what we can do , but If you stuck in frozen lake , means you do not have capable scanner to read anti theft module faults

You said you disconnected battery ,but have you tried like below procedure .

stuck on frozen lake ,could it be u had a weak battery and now battery is weak and read below 10.7 volts WHICH WILL TRIGGER ALARM , TRY RECHARGING IF ANOTHER VEHICLE IS AVAILABLE TO DO THAT OR CHARGER

Master Reset

1-Disconnect Both Battery Cables ,Positive & Negative .

2- Touch Cables With Each Other For 60 Secs ( this will take any residual power in the Harness to Reset the Vehicle Modules )

3- Wait 30 min

4- Close all doors and trunk

5- Reconnect Battery Positive First

6- Use The Key in The Driver Side Door

Lock Cylinder to Lock it & Unlock,IF You have only a Key Fob ,use it to lock and unlock

7- Enter vehicle and Start it .

if the above do not work , unfortunately You will need a Capable Factory scanner or equivalent to Read the Fault codes in the Anti theft module needed here ,that is done by hooking up the scanner to your vehicle DLC data port connector and based on these faults we can pull up a Pin Point Troubleshoot and be Accurate ,If you do get the Faults Read ,Please post them back here for me and I can Help You Further on it and send you the pin point troubleshoot to perform or the most possible causes for it .

Please Let Me Know

Thank You

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
