Thank you, thank you, thank you!!! I actually had to DEMAND that my boyfriend did this procedure. He said it was a waste of time. I had to stand and watch him take off both cables. The look on his face when it started was priceless. Girlfriend diagnoses problem, problem fixed... High five for girlfriend power!!!

OMG... You just saved me hundreds of dollars. I watched several videos. Nothing worked until I seen your video. Simply disconnect the negative battery cable for 5 minutes ... WOW. I have a Infiniti Q 50

I have the 2013 vw jetta 2.5 and Disconnecting the battery for a few minutes fixed mine as well. Unfortunately i took it to the dealership before i found this video and had to pay $125 diagnostic fee for them to tell me they couldn't figure it out but thier recommendation was i needed a new reader coil at the cost of another $565. I found this while i was waiting to hear back from them and told them no on that service. Thank you for the video you saved me some money and a huge headache!

Just want to add one more data point. 2014 Mercedes E350, no key detected, the fob works fine for locking/unlocking with a new battery. I did exactly what you said then it worked like a miracle! I watched more than a dozen YouTube videos, this is the only one that really works!

I watched a bunch of videos, got frustrated and then tried your suggestion. It worked, and was simple. Thank you.

Reboot your car?... Who would have thought? Well done. Saved me a trip to the dealer. Thanks.

Even after getting a second key programmed which I needed anyway but it wasn’t the key that was the issue. This was my last hope before calling the mechanic and it worked, thank you so so much, you saved me a trip and potentially hundreds of dollars just trying to get this diagnosed. I had a 2008 Mazda CX nine grand touring with the smart key.

Worked on my Hyundai Kona 2022. Context: I changed the car battery today. After that, I could lock and unlock it with the beeper but no key recognized inside the vehicle. This method fixed it and worked like a charm! . THANK YOU!

This happened to my daughter’s Mazda 6. I did what you recommended and ‘voila’ it worked. The Mazda owner’s manual told me to take it in to the Mazda dealer - so now I don’t have to pay AAA for towing and the dealer tons of money. This is such an amazing and easy fix!

[nihondragon]

You sir are a genius. I just bought a Honda with a smart key error message. The dealer did replace the battery and reset but connecting to the computer. All was good until the next day when message came back. I did your tip and it's all good again. Thanks so much.

Your video saved us a trip to the dealership and lifted a HUGE weight off of our shoulders! Thank you so much for posting!!

[scantillo]

Thank you! works perfectly. Only thing is disconnect negative first and then positive. After the 5 min reconnect the positive and then the negative.

[leonupton]

Did this after my key stopped being detected. Changed the battery key and it was still the same. So I disconnected the car battery for a few minutes and reconnected and it worked and no problems. Mine was a 2010 ford focus.
Very grateful for this video 😊👍

[EpochRecursion]

you have the only video with the actual and easy solution

We just had that problem on a 2009 Audi A4 after changing cars battery. I searched for the problem and Audi A4 key fob not being recognized by the car. Then I stumbled upon your video. We disconnected both negative and positive and sure enough the car started right up. Thank you so much

Brilliant...I'm going to try this. Have this error after changing my fob battery....it's been driving me crazy but do not want to go to dealership. Thank you for uploading ☺

[Saveryman]

You are the man. I just canceled my appointment with the dealership. Thank you so much.

[JeffHassmann]

Thank you so much for this video. 2012 Buick Regal went into no remote detected. Put the fob in the slot and car still wouldn’t start. Thought maybe the battery since I had not used the car in 10 days so I took the battery to have it checked and it checked out good so I put it back in and thought what the heck & pushed the start button and the car started right up. You saved me a lot of hassle so a BIG THANK YOU AGAIN. 👍🏻🙏🏼
