Going for scuba diving, how do I do with my remote control with integrated key?

[peterjaw]

Hi all,
I wonder when I go for scuba diving, can I take the integrated key with
me only and leave the remote control in the car?

My question is: if the integrated key is just an ordinary key, then this
probably fine; but if the integrated key has chip sets in the plastic area,
then it won't be a good idea to submerge it into salt water.

Does anyone has similar situation like me? Anyone can provide your
suggestion?

Appreciate for your help.
