Blmkso Posted June 7, 2017 Report Share Posted June 7, 2017 We are leaving the Edge at the airport for a week and was wondering if leaving the key fob in the car would drain the battery ? Quote Link to comment Share on other sites More sharing options...
TheWizard Posted June 7, 2017 Report Share Posted June 7, 2017 It will prevent you from locking the vehicle. Quote Link to comment Share on other sites More sharing options...
akirby Posted June 7, 2017 Report Share Posted June 7, 2017 It will prevent you from locking the vehicle. Not if you use the keypad to lock it. It disables the fob. It should not cause any extra drain on the battery but you never know. 1 Quote Link to comment Share on other sites More sharing options...
Waldo Posted June 7, 2017 Report Share Posted June 7, 2017 Yep, just use the keypad or another fob to lock the car and the fob inside will be inactive, so no battery drain. 1 Quote Link to comment Share on other sites More sharing options...

omar302 Posted June 8, 2017 Report Share Posted June 8, 2017 I'll just add a note, if the fob is left in the car & locked using the keypad, yes it disables the fob, meaning the if someone breaks in, presses the brake pedal & push start button, the can would not run. BUT, if the intruder finds the fob & presses the unlock button on the fob, the fob will work, it will disable the alarm & the car will start. So, as mentioned earlier, it will not drain your batteries (car's of fob's), but it is a security risk. You either should really hide the fob or you can remove the battery from the fob to render it inoperable, though you would still be able to start the car after inserting the battery-less fob in the backup slot in the center console. 1 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted June 8, 2017 Report Share Posted June 8, 2017 Some sources state that the fob continues to communicate with the car. http://www.chicagotribune.com/classified/automotive/sc-motormouth-autos-0616-20160613-column.html http://www.chicagotribune.com/classified/automotive/sc-motormouth-autos-0316-column.html http://m.autoserviceprofessional.com/article/94711/Today-s-key-fobs-smart-keys-Technological-advances-provide-convenience-and-cause-problems Quote Link to comment Share on other sites More sharing options...

omar302 Posted June 8, 2017 Report Share Posted June 8, 2017 (edited) I'm gonna test this theory and have my son go in through the windowAn easier way to test, leave the window open and work through it. Sit inside and lock using the keypad then test. Edit: note you have a 2015/2016 Edge, mine is a 2011. So they might work differently, but good to know how it will work.

Besides that, the system in the Edge is not an "active" system. It doesn't constantly look for the fob, it only looks for the fob when you touch one of the door handles.

enigma-2 Posted June 9, 2017 Report Share Posted June 9, 2017 Something seems to be broadcasting. Whenever I walk in the garage with the key in my pocket, the welcome light came on, and I wasn't close to the car. Quote Link to comment Share on other sites More sharing options...

It has a normal key, nothing being broadcasted. Quote Link to comment Share on other sites More sharing options...
Tightanium Posted June 10, 2017 Report Share Posted June 10, 2017 I just tried all kinds of scenarios. If the fob is in the car it will start. I locked myself in,had my wife key pad lock me in,used the fob to lock me in. Car always starts. I even tried it while I wasn't sitting in the seat, thinking that it may know someone was in the car when it was locked. I wouldn't leave the key locked on the vehicle. I have a 2016.

How long did you wait after locking? I think it takes some time before the alarm is enabled & fob is disabled. Also, it might be different being a 2015+.

omar302 Posted June 10, 2017 Report Share Posted June 10, 2017 Only a few seconds.This is from the 2011 Owners Manual, not sure it still applies, but you can try: When fully armed (after the 20 second pre-arm mode), any IA keys found inside the vehicle are disabled/inoperable and will not start the engine. Press button to re-enable them. Quote Link to comment Share on other sites More sharing options...

Sorry, should have bee clearer, I had a 2016 MKX for a few days (as a loaner). Yes, my 09 has the standard FOB. Actually, I prefer the "old fashioned" key. I found the IA to be a bit bulky. Also, it refused to start the car once, even though it was in my pocket. Car said there was no IA present in the car. (?) One other area I had trouble with was locking the car. I ended up locking the cat by pressing the FOB each time, probably don't know how to do properly. Quote Link to comment Share on other sites More sharing options...
omar302 Posted June 11, 2017 Report Share Posted June 11, 2017 enigma-2, newer Lincolns do have what they call "Lincoln welcome lighting" & "Approach Detection" that does exactly what you described. So yes, the car should be continuously scanning for a "transmitting" fob without touching the door handle. 1 Quote Link to comment Share on other sites More sharing options...
akirby Posted June 11, 2017 Report Share Posted June 11, 2017 To lock an IA vehicle touch the top of the door handle on the raised ridges. The fob has to be within 3 feet or so. Quote Link to comment Share on other sites More sharing options...
Mirage52 Posted September 22, 2017 Report Share Posted September 22, 2017 (edited) One of the things I loved about my old Edge and Mariner was being able to leave keys in the car and lock it so I don't have to carry keys around at a ball game or while I'm floating on the river. I was hoping to leave keys in car while at airport but it appears like this is a dicey scenario, at least to test it out. I guess I'll just have to lug them around Europe for 2 weeks.

There is no problem leaving an IA key fob in the vehicle & locking/unlocking via the keypad. The only security risk is if the intruder finds were the fob is & presses the unlock key which is the same risk if the found the key of a regular ignition vehicle.

akirby Posted September 22, 2017 Report Share Posted September 22, 2017 There may be a timeout period during which the vehicle will still start with the fob inside the vehicle. Try waiting at least 10 minutes next time if you test it. Quote Link to comment Share on other sites More sharing options...
Uncle Louie Posted September 28, 2017 Report Share Posted September 28, 2017 This topic is great. I could not pick up my 2014 Edge at the dealers so he told me he would leave the fob under the seat and lock the car. After I hung up I said hey that wont work and I was worried someone would find the car unlocked and go for a joy ride. Well when I picked up the car it was locked and had to use the keypad to get in and have been scraching my head saying how did he do that and read this topic and got my answer. Thank you all very much. 1 Quote Link to comment Share on other sites More sharing options...
David Young Posted October 24, 2017 Report Share Posted October 24, 2017 Good info here. My wife and I have been locking the doors on our (hers) Edge by pushing the last 2 numbers on the key pad, now we'll just touch the little buldge on the door handle.
