I finally found the exact battery I had before so imma try that but what do you think it is? Thank you!

Tough to say on that one. I have not encountered it only happening when the car is in a certain gear. But, Initial thoughts lead me to belive there may be an issue with a sensor. Which sensor... That is something I can't really chase down without seeing the car in person.

[@zretro-_rd5714]

No special tools needed. You either need a 3/8 or 1/2 inch wrench, or in metric sizes a 10 mm or 13 mm wrench. Most tool sets nowadays come with both. You want to use the one that is most snug on the nut or bolt. You can use a ratchet and socket or wrenches, whichever fits easiest.

Checked the car battery? Or did you disconnect the car battery for a few minutes? If you checked the fob battery, disconnected the car battery for a few minutes, then it is possible you might have to reprogram the key.

[@therep49er]

Unfortunately, this does sound like a mechanical issue. If the fob works for lock/unlock but not starting, I would bet it is the fob or the part that receives the signal for starting. That is a best guess though. Thanks for checking out the video and leaving a comment. Please check back and let us know what the issue ends up being.

Any help with my Nissan bluebird sylpy. I lost the key. And my car was grounded on the street for two nights now!

[@therep49er]

Unfortunately without your key, your only option is a tow truck to get it home or to a dealership/mechanic. The dealership can likely make you a new key based off your VIN number. A mechanic can possibly replace your whole ignition tumbler. But, if you need the original key for anything else (trunk, doors, gas cap ect.) you will still need the original key. So, best advice if your car is not already at home, get it towed to your Nissan dealership of choice and have them make you a key... Better yet, 2 keys. If the car is at home, get your VIN #, call the dealership and tell them your VIN and request a key. This may take one day... or 5 or 10? It just depends on what their process is and what they need to do.

[@randomcontentking9521]

So when this doesn't work and changing the battery doesn't work than what else could be the issue? Also does the battery have to be an exact match or does it not matter as long as it's the same size?

[@therep49er]

Make sure your key Fob battery is good. Your car battery has an "acceptable range" for its specs of CCA (cold cranking amps) and physical size that will fit in the car. Along with some other things. But, the CCA and physical size are the most common concerns. Top or side post doesn't make a difference. All that matters there is getting the same post style battery so you don't have to change connections.

I have a 2014 Lincoln MKS. I have an intermittent problem with both keys. I have new batteries in both fobs. Sometimes, I cannot open the locks with the touch sensor, sometimes I can. I can unlock the car with the fob from 30-40 feet away, so it has a good signal. When I get into the car again sometimes, I get the "No Key Detected" Error. When this happens, while sitting in the car, I use the fob to unlock/relock the car doors and it usually starts right up afterwards. I do not have any issues starting the car (when the key is detected), so I do not think my car battery is going out. I will disconnect the batty to reset the system, but I do not think this is the problem since it is intermittent. I disconnected the auto battery and place it on a trickle charger to top it off (suggested from another video). After 5 hours, I cleaned the terminals and hooked everything back up. Did not fix. I have the same issues with both keys. Suggestions, thanks.

Thanks for the video. This is the 4th time I have had this issue on our 2015 Edge. First two times the Dealer couldn't find anything, 3rd time, they replaced the battery in the vehicle.

[@therep49er]

Sorry you are having a rough time with your vehicle. My best guess and it purely a guess, since everything you listed has been done, the only thing that remains that I can think of would be some type of electronic or computer component in the car. If it is that, hopefully it is a warranty repair. Since this happened in my car, I have not had many or any issues like I was prior to disconnecting the battery for a few minutes. The issues I did have after resetting everything were likely because I walked too far from the car with the keys. In which case it was responding properly. Best of luck, hope the reset remedies your issue or that it is a warranty repair.

My driver seat moves every time i get in or out of car and that harness moves also since its clipped to bottom of seat and over time it caused a wire to sort. This harness comes from the center console to the bottom front of driver seat and its part of the cars immobilizer module that under center console.

Ive exhausted all other options so might as well ask here too.. We're having this issue with a 2015 Ford Focus SE and it keeps getting no key detected even though its got a physcial key. When it happens 3 other issues all come up at the same time, doors wont lock/unlock, blinker wil randomly stay on after completing a turn, and the hill climb assist disables.. All within a span of about 10 minutes these will all happen. The only fix seems to be D/c battery but the issue just eventually comes back within a day.. Brought to a mechanic and they checked battery, charging system, and electrical and couldnt find any problems. OF COURSE the issue wouldnt happen for them for the 4 days they had it so they were unable to replicate the issue and troublehsoot with it happening.. Any suggestions please! We've replaced the battery in the key fob as well just in case..

[@therep49er]

Well... This one is pretty different. Let me do some digging tonight while I am at work. I will see what I can figure out.

[@therep49er]

Is your Focus included in a "Door Latch Recall"? The dealership should be able to confirm that with just a phone call and your VIN#. A faulty door latch could cause the won't lock/unlock issue. For the "no key detected" since you said you have a physical key, I assume you do NOT have push to start? If you do not have push to start, do you have a spare of the physical key? If so, try the spare and see if the problem persists. Physical keys for that car still have a chip that transmits a signal when needed. If that chip is malfunctioning OR the vehicle has an electrical system issue, it can cause the no key detected issue. There is also potential that the keyless entry module is starting to go bad. Are you the only owner of the vehicle since it was new? Has it ever been in an accident? If you bought the car used, did it have a "rebuilt" title? If the car was in a serious accident, that can cause MANY little electrical and mechanical gremlins even after it was "repaired". For the hill climb assist... This also could have many gremlins to chase. Could be as simple as the Brake Light Switch needed to be replaced. That switch might affect your turn signal staying on to? It sounds like you have more than one issue affecting multiple areas of your vehicle. That is why I asked if it was in any accidents. I don't think you will get lucky enough to have a "quick fix" on this. I think you have many frustrating days ahead trying to chase and resolve these issues.

Re-connect the car battery and see if that solves your problem. If not, you may have to take it into the dealership unfortunately.

Somewhere in your truck there is a spot where the fob is supposed to go (even if it is dead) in order to start the truck without the ignition recognizing the fob.

Even if it is unlocking and remote starting the car, sometimes (on some vehicles) it still won't be recognized by the ignition.

If you disconnect the battery in any car. You automatically wipe the radio stations. And if it is a newer vehicle it has anti theft Built-in the radio. Would need to get the code from the owner's manual or the dealer.

In some cases you are correct. But, not all cases. It is extremely difficult to know all makes and models reactions with radios/anti theft when replacing/disconnecting the battery. But, I can tell you 100% for certain, 2010 Lincoln MKT has no loss of radio stations and no adverse reactions with any anti theft. This is also true for 2018 Chevy Silverado, 2019 Toyota Highlander, 2008 Jeep Patriot, 2013 Chevy Malibu, 2009 For Escape, 2012 GMC Acadia and Many other cars. 2004 Pontiac Grand Prix, you do run a risk of losing radio stations and triggering the anti theft system.
