Just like the title says. My door will not unlock if my iPhone is in the same pocket as my keys.

 

Just found this out last night. The interference from my phone interrupts the signal sent from the keyfob.

I have a Note 5 for those curious Android users as well.

 

I never noticed this, probably because I never keep my keyring in the same pocket as my cell phone. I can only imagine the horrific scratches lol.

 

Good to know. I wont think the TLX is malfunctioning and curse out the car or the ppl who made it.

 

It also doesn't work when I have the keyless fob to my wife's Mercedes in the same pocket.

 

Sorry...myth busted. It sounded implausible but I wanted to try.

I just put my key fob and my iPhone 6S (with cell, wifi, and BT active) in my pants pocket and every button works just fine. Lock, unlock, and trunk release work as expected.

The button on the handle to lock the door works too, as does the touching the handle to unlock...all with both fob and iPhone in my front pants pocket.

 

Looks like someones TLX is malfunctioning. i will put this to the test on the am tomorrow. I would go right now but 3 flights of stairs are in the way.

 

Yes sometimes it doesnt work when in the same pocket as a phone. Ive heard my dealer mention it plus read it somewhere else. It just varies on the signal not specifically iphone or what but yeah its a thing

 

I put this theory to the test today and it is true. The phone interferes with the remote signal. It took a couple of tries before the doors unlocked.
Thanks for the info

 

Yep. Same issue with my '16 TLX and iPhone 6s Plus. And with our '14 Jeep Grand Cherokee. Signal is blocked.

 

I must have a magic iPhone or a magic key fob. Mine works fine. Never heard of or had the issue with my Lexus or any other vehicles either.

Until someone can explain how a phone which operates on completely different frequencies could jam a key fob, and why mine works fine, I call bullshit, or coincidence, or wishful thinking.

 

I think if the fob is behind the phone, it may not work...for me it always works if the fob is in front of the phone.

 

Right. No fob fib here. If the phone is between the fob and the car the phone shields it.

 

Nope. Just tried with the fob closest to my body and the phone closest to the outer pocket cloth of my pants. Everything still works fine.

I'm not trying to be a jerk, but what you're saying makes zero sense from a technical perspective, since both GSM and CDMA phones operate on a much higher frequency than the key fob frequency (which is typically in the 300MHz range). WiFi is also much higher frequency.

On top of the technical questions, I have tried with more than one pair of pants, and put the key fob on top of the phone and under the phone. Everything works fine. Keyless entry via the fob buttons and touching the door handle both work.

Not sure what some of you are experiencing.

 

sell the car or sell the phone seem like your only two viable options...

 

 

I don't think it has anything to do with RF. My wallet will sometimes block the fob, Or my pocket with the fob will be turned away from the handle. Sometimes will not open.

 

almost every time without fail when i'm holding the phone and the keys with one hand the keyless entry will not work. wife on the other hand jiggles everything in her purse (including her work fobs) without the slightest issue. if I'd have to guess it's the direct proximity of the phone to the keys what causes the disruption; take them just a few inches apart and no issue even if the phone is in the direct path of the keys and the car. Never thought of it as a defect.

BTW why is this an issue? Any particular reason you need to wring both phone and keys in the same pocket?

 

I got into the habit of putting the fob in my left pocket and my Iphone in a lower leg pocket on my right side shortly after I got my car. I think all the fob buttons work, it just seems to interfere with the door unlocking when in close proximity to the car. Sometimes I'd end up doing a little dance to find the sweet spot to get the door to unlock. After keeping the devices separated I have no issues.

Don't know why it doesn't work, but it has no problems when fob and phone are apart.

 

My Miata had keyless entry also. My phone would mess with the key also. Always had to keep them separated.

 

anyone have issues with their NOKIA phone? lol

 

i put my keys in the same pocket and they come out a dust pile of carbon...

 

Happens to me a a lot. It also happen when i put my cell and my keys in the same pocket in my backpack.

 

The signal is so weak that anything will interfere with the remote.

 

I have an iPhone 6, and have noticed the car's button on the door not locking the door on the first try, but takes several attempts. Also the sensor on the handle can have a mind of its own. Sometimes it happens other times not.

 

Very strange. I have a note 4. Tested this today. Had the keyfob right next to phone in same pocket. With the keyfob in front and behind phone I could still lock/unlock the car. Bluetooth wasn't on at the time I think, so maybe that's a factor?

 

If the keys are close to the body and the phone is blocking the keys then the Fob does not work....

 

Again...maybe I'm special or I have powers beyond those of mortal men, but I have not observed this, and mine works fine.

 

Exactly the same experience and it's very consistent. I've just gotten in the habit of sliding my phone behind the fob (so phone is next to my thigh). Fob never comes out of my pocket.

 

also, i have another FOB for a different car.... I think they may interfere with each other.

 

I have also had the same issue on my '15 TLX although I have not tried to repeat it yet, but now that I have seen this thread I will try it more often. Interesting enough I never had this issue with my '09 TL.

 

Well as you can see there are many other people who experienced the same thing. So I fear you are presuming your knowledge or radio signal interference is greater than it is.

 

Has nothing to do with knowledge. I've never been able to reproduce what others claim (with this car or any other car I own now or have owned previously), and it makes no logical sense. I can't speak for the other people's issues.

 

Not trying to be a jerk here either - but this has everything to do with knowledge or lack thereof.
You hypothesize that the observed results make no logical sense - this is based on your presumed knowledge.

The result under discussion is a FACTUAL observation reported by multiple, independent sources.

That you don't understand why this happens is irrespective of the fact that it does happen.

That you cannot replicate the result simply indicates something is different with your test conditions.

FACT: When my phone is in my pants pocket with my fob, the car will not unlock when touching the door handle about 20% of the time.
FACT: When my phone is in my shirt pocket, I have never had a failure to unlock.

 

Again...the fob and your phone work on two completely different frequency spectra. The fob uses RF and the phone uses RF. If there was an inherent interference or issue, then why wouldn't there be a problem 100% of the time?

I have never had the issue. Not once. So using your logic, my 100% result is more consistent than your 20% result, so maybe the problem is yours?

I'm trying to be a jerk either, but when people make illogical claims with no basis in any technical reality and I try to objectively reproduce the problem and can't, my conclusion is the problem is localized.

I'm done arguing.

 

Yep - arguing on the internet is an exercise in futility. In any case, your logic is flawed and doesn't meet scientific rigor. Cheers, out.

 

it happens to me too. i can't open the trunk even with the key in my pocket sometime.

 

I wa schooled as an Electrical Engineer, though it was not my career. There are LOTS of ways they could interfere, other than via RF transmissions interfering directly. EMI from the phones digital systems, for example, might interfere with the fob. Also, two signals occurring at the same time also create sum and difference signals, and that provides more ways that might upset things. The antenna in the phone might also absorb energy from the fob. There are just so many ways these things can happen. Peronally, I have had it happen in my new TLX a couple of times, where touching the inside of the door handle did not function as expected, always when the phone and fob were in the same pants pocket. Never a problem when they are in different pants pockets.

 

Put my phone and fob in same hand or pocket and the touch sensor on door does not work.

Separate them and it all works. Just a pain in the ass.
