    Pitfalls of Keyless Ignition

    Done it again - I must be more careful closing windows at night, open to prevent heat build up in the car. For some reason I find myself forgetting to turn the ignition off after closing the windows when putting my CTS to bed in the driveway. I get in with keys about me, turn ignition on, and close the windows. Then I usually hit the easy/exit button to return the seat to normal entry position. But w/o using a key to turn ignition on, I have forgotten to turn ignition off. I dont start the car but just turn ignition on while straddling the front seat. Then get out.
    Only by sheer luck did I later notice my headlights on(now dark outside). Dont know how long lights were on. There doesnt appear to be an energy safeguard to turn them off after so many minutes if ignition is left on. Battery Saver Active was in the DIC indicating EPM was trying to do its thing.
    Turned car on and ran a bit - voltage a little low just below 14.0.
    Of course in the old days we would turn car off and remove keys. Done this twice now over the past couple of years.

    I thought it would still shut everything off. When I just got the car and I was transferring music to the HDD it would sit in the garage with the ignition set to ACC.

    After a while the headlights would go off, the the interior lights would come on, and then everything would go off.

    Now after typing all this I realize you probably had the key in the ON position.

    Re: Pitfalls of Keyless Ignition

    According to manual:
    To keep the lamps on for more than
    10 minutes, the ignition must be in
    the ACC/ACCESSORY or ON/RUN
    position

    So I based my comments on that info. But things may change if you are in car with door closed doing something versus turing on ignition and then exiting vehicle. It would seem logical that as part of all the power saving controls/features that at some point the lights would go off or at least change to parking lights. Not something I plan on checking.

    Re: Pitfalls of Keyless Ignition

    Sadly or ironically, i just this yesterday and needed to get vehicle jump started.

    My second time as well, so don't feel bad you have others that feel your pain.

    I blame Caddy...they make the car too simple. I walk up the car and it unlocks...i walk away it locks, headlights and wipers turn on automatically, i just need to remember to steer the car, it does the rest. So i blame Caddy for making me forget to turn the ignition off...it should do this too
    mnmjack and arachnyd like this.

    My Mom has a 2005 STS and when you leave the car on and walk away from the car with the key fob it sounds the horn with 3 quick blasts. The DIC also gives a message about no key fobs present. I don't recall if that happens in accy mode or only when it is running. It does shut down after 10 min. or so when just in accy. listening to radio. Drove me nuts, had to keep pushing the button to keep listening over the half hour I was waiting with the car. But in the end with all the little features you can change with a Tech 2 or MDI every car can be unique.

    The easiest way to prevent this and lots of other things like forgetting to completely close a door or two is to get in the habit of listening for the confidence horn beep as you walk away. If it doesn't beep then you did something wrong.

    I actually have the beep turned off. Only have the flashing lights.

    Re: Pitfalls of Keyless Ignition

    On my STS, I can put up all the windows from outside the car using my FOB - I would bet you have that capability with your CTS also. That's a handy feature, especially when you leave your windows lowered some while at work - and a storm comes up, I can raise all the windows from inside my office.

    Re: Pitfalls of Keyless Ignition

    I have had this issue as well on my 09 CTS-V. I turned it on long enough to get my current mileage. Shut the door and forgot to turn the ignition back. An hour or two later I saw my headlights were flashing. In addition, my locks were ticking like it was constantly trying to lock or unlock. When I got in my car it said the theft "whatever" was activated. Then the car shut down, I couldn't do anything, including pop the trunk in order to charge the battery. I had to reach through my back seat and pull the trunk release, charged it and all was back to normal.

    I am also having a terrible time with the Fob not being recognized and my car locking even though the Fob is in the cup holder. I was so lucky, that on Easter Sunday, I had both sets of keys with me and it didn't recognize either set, and locked my car. First locksmith was unsuccessful and caused $300 damage to the trim around my windows. Second was better and got it unlocked for me. Of course the dealership cannot recreate the issue, for which it happens so often, I had to get OnStar activated so that they can unlock it for me Anyone else experiencing this?

    Given the key doesn't work if you have an iPhone I think the whole idea is idiotic. How hard is it to put the key in the ignition or press the button to open the doors? I have been locked in the car when my wife took the keys and she has been locked out when she left her phone AND keys in the car. What a terrible idea. My Ducati. Does the same thing. Won't start if I have my key and IPhone on me. It's a joke. You still need the key for luggage or gas cap, so wtf do they come up with this for? My old Chevy works fine with a key. My VW is busted up to where the doors don't open or lock yet it still works fine to put the key in the ignition to start.

    Please bring back keys.

    My suggestion would be to replace your FOB batteries...never experienced that issue.

    Who ever told you that an iPhone had anything to do with these issues pulled one over on you. That's just ridiculous!!
