Its ironic how I call my jag Jagtanic and my washer killed it, anybody know how to fix a water damaged key with little to no money involved. Urgently need fix

 

Urgently fixed why? You can manually use your key while orchestrating the fix (or money to replace it) of your fob (if possible).

May I suggest reviewing this from the How To section (listed in my sig)... https://www.jaguarforums.com/forum/x...ir-kit-177521/

 

Here is what it does

 

The car is on its 3ed owner and only has one black key

 

That then is your security module, different story. You can try to old put it in rice (like a wet cell phone) and see if it gets the moisture out of it.

 

Drop it into a small jar of Isopropyl Alcohol ( common rubbing alcohol ) overnight to dissolve and displace the water . Then put some penetrating oil to protect the inside component

 

I live in San Antonio I have lots of that I will give it a try and to answer you other question it is my last working car and Monday is just around the corner

 

Unfortunately I don't have any of that and all my cars are either in the shop of have flooded keys

 

I know there's another thread on this where they broke the key apart at the module so you could see what it is. But since I can't find that, this one may give you a better idea at least. https://www.jaguarforums.com/forum/x...uctions-90880/

 

Hair dryer -- warm not hot. Pray ... I assume the security module is not able to read the key's chip.

This is why you need two keys .... even if one is the valet.

 

Here's a simple definition of how that module works in cohesion with your ignition:

• Simplified: Once the key is inserted into the ignition lock and turned the ‘on’ or ‘run’ positions, the induction coil mounted around the ignition lock sends out an electromagnet field of energy. The windings in the transponder chip absorb that energy, power the electronic chip to emit a signal (usually an alphanumeric code). The induction coil reads the signal and sends it to ECU to recognize the signal. If the signal is recognized, the signal is accepted and car starts.

So as long as your module is good and only coated with the water, drying it should alleviate the problem.

 

I just bought the car 5 months ago all I have all plans I don't even have the plates yet, I do need to get keys my guess is jagbits will have it or barret jaguar

 

I will try in the morning and see if the rice worked, should have got the rental car from jaguar instead of an uber after I left my s type their for a new starter

 

Drop it into a small jar of Isopropyl Alcohol overnight to dissolve and displace the water . Put some penetrating oil into it to protect the inside RF chip .

 

All I know is that it does some stuff wipers went on, lights whent off and the engine turns over ones.

 

I don't have that and both my ford and jag keys dont work so I can't get out to get some thanks for the suggestion though

 

Here's what's inside, next to a standard toothpick. Looks sealed in a capsule so it is not clear how water would go in. Possibly, it is water inside the key head surrounding the capsule and blocking/absorbing the radio waves. Another possibility is that the temperature inside the washing machine damaged/melted the plastic capsule. I would put the key in an oven at about 50C and leave it for a number of hours.

 

There is a rattling inside the key
Here is a update to what yhe car does now

 

Here is what the car does now a bit better but no start

 

Based on what I hear and see, number one check is battery voltage - what is your car's battery showing (have you a multimeter?)

Number 2 - the key module housing is glass, that sounds like it's broken. Have you any mobile locksmiths, specializing in cars locally? A forum member recently posted a brilliant service that pulled the chip's code and cloned it onto a blank then cut the blank, I'll see if I can find it as it may be of help.

Personally I think the key's module is trashed for starting the car, it's shouldn't ring like in your video. It can still be used for trunk, glovebox and drivers door though.

The dealer should be able to pull the key code and supply a new key but you'll need to be sat down when they hand you the invoice.
