    Hello, I purchased my first 4Runner last Spring, a 2014 Limited. This year, our neighborhood has been having a rash of crime including home and car break-ins. A few times, I've gone out to my car in the morning to find it unlocked; a couple of times I found my glove box and/or center console open, so I know someone was in my car. It is "possible" that I didn't lock it at night, but I am 99% sure that I made a conscious effort to lock it when entering my house for the evening. The alarm never went off, and nothing with the door or window appears broken/tampered with.

    I am wondering, are there any known vulnerabilities with this particular model 4Runner when it comes to criminals gaining easy entry? Is there some high-tech RF gadget they are using to unlock it? I'm really perplexed on this.

    Thanks for any feedback!

    I've seen stories on the news about keyfob cars having this vulnerability. My guess is that the comms between the fob and the car don't use any hashing, encryption or frequency hopping so the signal is simply intercepted and replayed, unlocking the doors. I would guess that a 4runner is as susceptible to this as any fob car and that in the future, manufacturers will be forced to address this.

    My workaround for now is a physical barrier. I park mine in the garage, so nobody even sees it. I suppose if you're without a garage, that could limit your options.
