    I was rinsing off my car when suddenly I heard a continuous alert. When I opened and closed the door it turned off but again it started when I resumed washing. I finally figured out that it was because I had left my key fob inside the car. When the water touched the handle it thought I was trying to lock it and alerted me because the key was in the car. Once I removed the key from the car, it was okay.

    I had read (in the manual, I believe) that going through a carwash can cause the car to repeatedly lock and unlock. Is there anything that can be done to prevent this, or the continuous beep, from happening - apart from not going through a carwash? This didn't happen with the Gen II.

    Keep the key fob away from the car. Happened in my GII as well so I just leave the fob in the garage while the car is getting rinsed if the driveway. Without the fob near the car it can't lock and unlock itself.

    Yeah...but I can't keep the fob away if I'm going through an automatic carwash! I took my Gen II through many times and it didn't happen.

    Oh, I took the rinsing off part to mean like you were doing it in a driveway or something. What are you using, one of those car washes where you put the quarters in?

    Yes, I was rinsing off the car in my driveway, but I figured out that I had to remove the fob from the car.

    However, my question referred to driving through an automatic carwash. No, not coin operated -- you pay an attendant and then drive through a tunnel and get washed. You have to be in the car so obviously the key is also going to be in the car. How does one prevent it from either sounding an alert when the water jets or cloth washers touch the sensors or causing the doors to lock and unlock repeatedly?

    You turn the car off while going through the car wash? We have those kinds around here but the car stays running while going through... While the car is running it shouldn't do that or else it' be beeping everytime it rained out lol. If you are turning it off, maybe just leave it on with no a/c, heat radio etc so it won't drain the battery since it isn't in there all that long.

    That sounds like a gotcha on the gen3. It wouldn't be a problem on the gen2 since you need to press the black button to lock it before water can unlock it; and then it can automatically re-lock if a door is not opened and repeat.

    I guess you could remove the fob battery or shield the fob. Or, find a location inside the car where the fob isn't detected which might be easy on a one door sks system.

    I had the same issue the first time I washed the car,and as soon as I heard it, I remembered the part of the owner's manual that talked about this.

    No, I don't turn the car off -- I put it in neutral.

    The Owners Manual does address this problem on page 50 and 51:
    • The doors may unlock or lock if a large amount of water splashes on the door handle, such as in the rain or in a car wash when the electronic key is in the effective range. (The doors will automatically be locked after approximately 60 seconds if the doors are not opened and closed.)
    • If the key is kept near the vehicle while it is being washed, water appplied to a door handle mahy cause the door to lock and unlock repeatedly. In this event, place the key in a location 6 ft. or more from the vehicle taking care not to lost the key. [No-duh!]
    • If the key is inside the vehicle whle it is being washed, water applied to a door handle may cause a buzzer to sound. In this event, locking the doors will cause the buzzer to stop sounding.
    Okay, I guess the first bullet means that if you are inside with the key, water appllied to the door handle could cause it to unlock and lock but after 60 seconds the door will lock anyway. (But notice is says that heavy rain could also cause this to happen.) And the third bullet means that if the alarm sounds, just lock the door and it will stop.

    I just keep the fob in my pocket while washing it. Yes, it'll "talk" to me from time to time, but at least that gives the car some personality.
