As I write this, it's nighttime and monsooning here, else I'd be outside making a fool of myself for the neighbors by assuming the position you see above. So, until more reasonable conditions arrive, I'm putting the call out to you readers. The video embedded after the jump shows a trick that apparently works when you're having difficulty unlocking your car from a distance. Simply hold the keyless entry remote under your chin and try again. Apparently, your cranial cavity helps amplify the signal and boosts the unit's range. Pretty cool, even if you do look like a bit of a tool while you're doing it.

Your assignment: before-and-after distances in the comments. Go!

Thanks for the tip, Chad!

      Thanks but not thanks..With the constant use of cell phones and Bluetooth headsets I have enough radio waves going through my cranial cavity already .

      Someone told me about this trick back in the 90's when the battery was going low on my remote. It worked for me until I could get a new battery.

      There's a video clip of Jeremy Clarkson from Top Gear doing this. He claims it doubles the unit's range.
        • 7 Years Ago
        It wont double your range, but it does absolutly work...for some reason.

      I've also been doing this for years. Something about how putting it there allows the fob to use your body as an antenna... of course you can look less silly by keeping your mouth closed while trying it.

      Know what works even better than holding it up to your head?

      Holding it ABOVE your head.

      It's all about getting the transmitter a better path to the receiver.

      Superstition FTL...

      Yup...been doing this for a loong time with my alarm fobs. Works like a charm. Not sure if I have any long-term brain damage from it, but at least I can unlock my car from long distances! LOL

      my keyless remote does not work, i changed the battery and no go, now what????
      • 7 Years Ago
      Yeah, I've been using this method for quite a while as well. It really helps get the most out of the batteries in the fob, especially when you're to lazy to put in a new one.

      Why do you want to unlock you car from so far away anyway? I never unlock until I'm next to the car. I'd hate for someone to jump into it while I'm still 400m away lol.

      The problem with my RKE is that is has trouble picking up the signal. I just tried this and it only improved the range as I kept walking away. Once I paused, it wouldn't unlock till I am right beside the vehicle. The dealer has preprogrammed the receiver and the transmitter but it had not improved this at all.

      I must say I side with the height hypothesis because by either holding the key fob to your chin or just holding it in your hand, it still results in the key fob being in direct contact with your body. Thus, if you think your body acts as an antenna, then it shouldn't matter whether the fob is at the bottom of the attena or the top (i.e. you car radio will not get better reception by attaching it to the top of the car's attena instead of through the bottom--if you have the old-school type). Or even better, why the need for an antenna if your entire car can act as one.

      Also, one time I was on the highest deck in the Queen Mary in Long Beach and I pointed my key fob towards my car on the parking lot which was about 400ft away and it worked (I doubt the entire ship acted as an antenna). Height is probably the most reasonable explanation for this since the higher the remote is, the clearer and more direct path between it and your car to transmit the signal. Of course there is a limit to the height you can reach before you start to be out of range. Think of a hemisphere around your car as the range, with the bottom portion crowded with obstacles and interferences and the higher portion free of obstacles.

      And in case anyone wants to prove otherwise. Try lying on the ground and hold the remote to your chin (on your back, stomach, side, kick your legs up in the air...you choose)...Let me know how it goes.

      This works on my Subaru SVX remote.
