“Dont get caught up in all the bullshit”-Bernie Thompson Words to live by

[@PineHollowAutoDiagnostics]

Love it 😁

[@simonedwards5401]

Great video We’re the 4 keys from dealer ?

[@rauls300ce]

@@simonedwards5401 yes the last guy did not program the key fobs to the right module, but did he try reprogramming the supposedly bad key fobs? he never mentioned it. and I was wondering.

[@jessemackenzie6516]

YES...... I love seeing Bernie on my playlist

[@PineHollowAutoDiagnostics]

Nicely done Bernie. Junk aftermarket parts strike again 😉

[@keltecshooter]

Wow, the break in the K line is something I will never forget.

[@smartnwogu8316]

Bernie, I love your teachings so much, you make me learn anytime I see your videos. I need a scope to do all these things I learn from your videos. It cost an arm and a leg from a brother in Nigeria 🇳🇬

[@daveunbranded]

Bernie is a living monument that can never be replaced

[@richardnilsen5]

The locksmith thought he was skilled. Not Bernie whooped them like a red headed step child.👃😂😂😂😂 Great video

[@Mr.G-]

Thanks and appreciate you for sharing your knowledge and expertise in automotive electronics and diagnostics.

[@robertmobileman8304]

great diag video Bernie , great step by step , awesome thanks for sharing your expertise and knowledge, good job

[@bettylane1984]

Another ,second to none case study with the master at the controls! Thank you so much!

[@theadmiral5425]

I'm not sure what equipment that locksmith has but mine can verify if the fobs are the correct type and if the programming was successful. I also own a scope and bidirectional scan tool to be able to diagnose these problems like you just did. I know there's a lot of counterfeit product out there so be careful what you purchase.

[@mr.hammer7080]

Why didn’t the 4 key’s work

[@mechanicalsuntheoneyouknow]

Big fan of the channel for years,Truly loved seeing all your videos. ,industry skilled professionals technicians, are dying breed I Love seeing you and everything you doing on your channel, fundamentals and use of a lab school has been principal for me for years. Thanks

[@ThunderbirdRocket]

Super helpful ! Informative and inspirational coaching cues !! Thanks-a-million Bernie ! I’m finding that I can apply your lessons because of the extraordinary detail that you provide ! 🏹🎯

[@ericwalpole4601]

Wonderful video. I love the point about staying on the facts versus popular opinion.

[@vickenkaragozian2041]

That's just amazing. That's what i wanted , somebody to diagnose antitheft system with a lab scope and showing to us. Most videos out there show how to program a key but nobody posts a video about trouble shooting the key fob or anti theft system. Bernie is just amazing and shows us exactly how things work and how to diagnose it.

[@jasonwember9927]

We're the 4 bad keys aftermarket knock offs?

[@stanleysemchenko4079]

Right I'm wondering the same shit.. that's pathetic if all of those bad keys were straight from the Chrysler dealer.

[@jasonkeith674]

Thank you. Very helpful. 🙏🙏 Is it possible for a key to go out randomly when the jeep is parked for two days. My situation. Parked jeep. 2016 75 Anniversary Grand Cherokee. Parked it for a couple of days. When to start using keyless remote start. Nothing. I got inside, foot on break, pushed button, gauges seemed normal, fuel pump kicked in, NO CRANK. NO BUS on display. Shop has had it several weeks and he told me today that he has no clue. Says he can’t even get his snap on reader to connect to ecm. I’m beyond frustrated. I’m mechanical and savvy at doing pretty much all my own repairs but didn’t have time to mess with this at the moment. Full time Paramedic and I’m getting as much overtime as I want right now. Any advice would be greatly appreciated 🙏

[@OzMechanics]

Is it possible that someone disconnected the modules causing those lost communication codes ?

[@car-key-programming]

Really good information there. I always like to see a good canbus diagnostics, and what you just did was a top-notch diagnostics. I thank you, sir. Had a similar case with the exact symptoms but it was not a key issue it was a rf antenna signal missing, prior shop erased all the dtc's thinking it would help and then I had to work without any dtc's, but thank God for technology, I was able to find the issue, it was a non functional antenna, repaired it and customers key started working again ( no programming needed ). 👍 the similarities in symptoms are so close that if you blink, you will miss it unless dtc's are present to help save the day, maybe. 😊

[@gerrymoeller]

Those keys may have the correct frequency to work the remote but it has the wrong RF ID chip. Not all aftermarket keys are the same and just because the company says it fits doesn't mean they are correct.. ran into this issue on a 14 Cherokee. 3 different brand aftermarket keys but only 1 of the 3 would program even though they all said they would fit..

[@advancedleveldiagnostics]

Great job, Thanks for Sharing! Did you check the old key to see if it was the same as the new one you programmed?

[@brentowen9480]

You are absolutely THE master Tech. That said, seems like you could have diagnosed a lot of that from the driver's seat without pinning anything. I appreciate your approach being able to prove what's working or not. I'm no where near your experience or knowledge but seeing what we had here, I think the scan tool should have been your first thorough diag tool. Great Vid, thanks.

[@brentowen9480]

and maybe you're just adding the scope in for advertising your tool. Which, backs up your position as THE master a you make great tools.

[@brentowen9480]

Okay I watched through the end now and will eat everything I said. Bernie uses the scope to gather data whether wrong or right to know for future use.

[@timothybarnes533]

I have learned so much from this man

[@gonzaloroca4126]

I've been following you for a long time, thanks for the knowledge that you share.

[@mikechiodetti4482]

When you know what your doing the job is much easier. Thanks for this video.

[@R3YNZ]

Were the 4 other keys aftermarket?

[@Mr2004MCSS]

That is what I was wondering too.

[@theblacksheep8473]

Nice love seeing your videos I fixed alot of cars using process

[@OnlineMechanicTips]

Good stuff Bernie

[@IamDerick]

Good advice for any sort of troubleshooting. The story can help but you cannot assume anything. Thanks.

[@p-san]

Great video. My few hang ups. Who attempts to program 4 keys? How come the question wasn't asked at the second key "perhaps it's not the key" and lastly, we're 4 aftermarket keys attempted to be programmed, or 4 factory keys? This would have been useful information from the start.

[@vickenkaragozian2041]

Nice to see you back Bernie. As always brilliant and very informative.

[@johnbriscoejr9738]

Hey Mr Bernie, you said don’t always rely on DLC because it may not be connected to the CAN BUS but to an interim module couldn’t you have pulled up a wire diagram first to see if DLC is linked to CAN BUS?

[@JoelAutomotiveInaction]

Thaks mr Thompson for another great diagnostic 😊

[@ralfsautomotive]

Who programmed the Key? I would have started by checking for signal with the keys. If the Original key was lost and the vehicle ran fine before I would not automatically assume that modules have gone bad. Maybe I am missing something.

[@MississippiWopGenius396]

After replacing the fuel pump Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.

[@godiagnostics]

Awesome stuff as always! Question, with the CAN not looking as 'busy' as expected, is there a general rule of how much comms should be seen on the line with KOEO, or is what you're seeing based off experience? I'm assuming the more modules the more data packets, but just curious!

[@isalmankhan1]

Great video as usual Sir, Thanks for sharing😍

[@martinboucaud679]

Great job my friend. I learned something new.. thank you for the knowledge.

[@Pablo_Automotive]

Thanks for another Great class and explanation

[@bbeauregard4181]

Always a pleasure Bernie!

[@miguelparedes1888]

Hey Bernie, I like the video and thank you for sharing your knowledge and taking the time to explain your diagnosis approach . One thing I’m not so sure about is that you mentioned that the locksmith that programmed the 4 keys is pretty capable but in reality I’m not so sure about that since they actually make tools that can check keys to see if the chips are good or bad .

[@deeznutz3494]

What if the “bad” keys were emitting a signal, just not the correct signal for that car? I think we’ve witnessed this in one of these videos, where the key wouldn’t program to the car because it was the wrong one for the car. The signal of the “bad” key was good, but the car didn’t like it. Sometimes the scope isn’t going to provide all the answers you need, and you have to go with your gut and/or your cheapest, most logical option

[@georgeschmitz4422]

Hi Bernie, You're always on target without fudging around. Like the information and always find something within to relate as I'm chasing the sometimes illusive problem. I am wondering, are you using an alternate scanner or exclusively the ATS Scanner for Bidirectional?

[@vickenkaragozian2041]

That is aftermarket scanner. The ATS scanner is generic scanner and it doesn't do output tests. It has to be an aftermarket scanner like Snap On or any other scanner with full function capability. He's using Autel scanner.

[@Paul-gw6ow]

Thanks for sharing that one .

[@alrifainidal]

super man . I like the way you diagnose the cars

[@ritchieschofield1185]

They say never meet your heroes. Well I'd love to spend a week with him. I'd learn so much but probably drive him insane 😂. The absolute master at automotive diagnostics

[@markferraro5250]

Would an AUTEL I key programmed with Xhorse or AUTEL km 100 have worked Thanks Berniegreat video

[@mikecatg]

Why can’t there be more mechanics like you out there? I get so tired of taking my Jeep in for service and all they want to do is rip me off.

[@poweredbyford87]

Yay a new Bernie video! 🎉

[@DirtyWorm12]

Hes back!😊

[@Hurlburton]

Yes this shop can handle the repair

[@pantelis241]

Thank you for the know how that you deliver 😊

[@kevincampbell8298]

The big break in the wave form is the car giving the key the finger… 😂😂😂

[@MdRubel-gy8ms]

Hello sir I'm mdrubel mechnice from bangladsh good information

[@daveyt4802]

Wondering about repos (stealing them back for the bank) with no keys. Now what??

[@DependableAutoTruck]

things were so much easier when a bus was what you rode to school or took long trips on and didn't want to drive.

[@ganeshnarayan5505]

Another great video.

[@michaelfrancis3261]

Wow this was so cool with the K line, 4 BAD keys wow

[@gmtech2012]

How are you supposed to actually know if you're looking at enough packets of data? That's mind blowing. Like how do you learn something like that?

[@tracycolorado]

Hey , Bern. 😊 you tha man

[@ibrahimwaheed987]

Thanks for the information you’re priceless

[@jimgeorge4677]

I love you Bernie.

[@ourtexasfamilyvideos62]

Had the same thing happen with my 2015 Kia. Locksmith tried to program 3 keys, all aftermarket. None worked. Had to get a factory key from Kia.

[@angela-z8u4g]
