2016 F34 w/ comfort access.

So after searching for 2 days, I found my key in the dishwasher. Unfortunately we ran a load of dishes before we noticed it.
After much drying and hot airflow, the remote buttons still do not work.
However, the vehicle still starts when I hold the key to the ignition.

Is there any series of steps I can do to get the remote to function to at least start the car normally with the comfort access, other than buying a $420 key from bmw?

Thanks guys

Make it the spare and use your other one for comfort access?

Does everything inside look ok? New battery too?

Clean your battery contacts inside the fob and try again?

Did you change the battery?

Last thing to check.

[Medic-NY]

I have not replaced the battery yet.
Going to do that this morning now that I can drive it.
I don't have a spare key. Only had one when I bought it.

Put it in a bowl of rice and bury under the rice for 24-48 hrs.

$371 + tax for a new key with blade cut to your car. Order it from a dealer. Don't let them "program" it. You can sync it yourself. Never know when you need a spare.

But definitely try a new battery first. I think the key requires a certain voltage for NFC stuff.

Put in a new battery, and surprisingly, it works!!
But yes, I'll be ordering an extra one soon!

Yes, the water can short out the battery exhausting it's stored energy which is why I suggested.

Still not a bad idea to bury in white rice (not cooked) for several days to get all the excess moisture out.

I save silica gel packs from random packaging for just-in-case scenarios like this.

The PCB for the key fob us encased in a water-sealed coating; liquid would not really harm it.

Impurities from dirty liquid or soda can cause the buttons to become stuck but it would not have any affect on the actual electronics within the remote.

Never heard of rust and corrosion I guess.

The contacts are aluminum and copper, which doesn't rust and is also coated but can form corrosion, had it been left unprotected.

Correct me if I'm wrong but I never heard or seen the innards of any keyfob rendered disabled due to oxidize corrosion build up..

And what happens if moisture in the unit not dried out gets to the battery?

Guess you're the only one to never see battery corrosion on a battery and contacts.

I give up; I thought maybe you just wanted to brainstorm the remote's infallibility but I see you just want to engage in sarcastic banter.

If the battery leaks and corrode the connectors, that has nothing to do with the engineering behind the remote, you're overreaching in an attempt to spike my claim.

I win no prize if I'm right or wrong, just wanted to share what I know, as I would hope someone would of educate me, had I been oblivious.

My whole point to this is the remote is designed to resist liquid. If it didn't, 1/2 the people here would need new key fobs, by now.

Trust me, I tried to destroy one in the name of science and it would not budge; it's built Ford tough.

That's funny. As you are so educated on this, trying to destroy a key fob, why did you wait 48 hours to post your "insights" until after the problem was solved? You certainly were posting in other threads the whole time. Even "assuming" in other threads....but not solving the problem here with your "facts" until after the issue is solved.

Just because the PCB is sealed, that DOES NOT mean all the moisture is out of the FOB itself. In fact, no matter how well the PCB is sealed, moisture from the other NON SEALED areas of the key fob will be attracted to the battery causing corrosion.

That's why I stated that it should be put into white rice as a safety measure.

And again, you must be the only person who's never seen a corroded battery leak.

Why is nobody asking the real hard hitting question here... HOW did the fob end up in the dishwasher?

That's easy - he wanted clean keys. It's a hygiene issue (haha)!!! I was wondering the same thing.

Why can't you just use the old key blade it should be fine just need to program a new fob. Do they sell them without the cut key?

[chowser51]

Yes they sell them without the blade but I thought he would want a complete key since he only has the one. I bought my car used and it had one key so I went and bought the complete key. Synched it myself. Wasn’t paying the dealer.

Damn OP... very lucky still.... just battery and everything working.
