Chipped Keys?

Does anyone know if the new body trucks have chips in the keys? People were told that the classic style had chips, but they didn't...i made many a key for my old trucks. Just got a new Duramax Crew and would like to make a key (I have my own machine) and not pay the dealer the $72.90 for an extra. Anyone know for sure, or should I just make one and see if it works? Thanks a million! Tom.

I am pretty sure they do. The dealer said not to copy them even on mine a 99, but idn if their lying or not.

 

 

I'm pretty sure there is not one in yours, I've had 3 (from 99-04) and copied all of them without issues; so if you need keys, go to the hardware, the cheap ones work just fine. They changed the key design a little with the new body style...I think I'm just going to try it, what's the worst that can happen, it won't start?

I've had a couple made for my '03 1500HD at Lowe's with no problems. Unlocks doors and starts the engine. :puke:

Even if you copy a "chipped" key you can still unlock the door if you're locked out (that is, if you're done paying for OnStar :cool: )

Maybe just make sure that running the original key on the machine will not damage/disable the electronics, if it's really there.

Why not just make one and see? Looks like you have the upper hand here with the key making materials in hand. Let us know how it comes out... We'd all like to know the answer.

I know I was told that on a 2000 Lesabre that you could unlock the doors with a key that wasn't chipped, but if you tried to start the car, the car would go into somekind of theft lockdown mode, where it would lock the ignition and wouldn't start until you took it to the dealer. I was also told you could reprogram the keys that have the chip, but just aren't programmed. In my car you would start the car with the already programmed key twice, and then start it with the new key, but I wouldn't try it, I wouldn't want someone with a tow bill because of me. LOL

Did you notice any smoke in your farts soon after that?

Sorry... just a silly joke. Ya know - like somebody was blowing smoke up your a$$ telling you that the car would somehow self destruct if you used the wrong key.

Had a regular $2.00 key made at my local hardware store for my 04 and it

worked fine. Haven't had one made for my 07 gmt-900 yet.

Alright, received the key today, cut it, and....no dice. GM has, unfortunatley, made it more expensive for us to make keys now. I can open the door, turn the ignition on but it won't even crank. "Service Theft Det. System" appears in the DIC. Oh well, it was worth a shot. Called the dealer and they said $50 to program the extra key. Oh well, thought I would share. Take care all, don't loose those keys.

Typical... Thanks for letting us know.

For my 2004.5 3500 SRW I have always been concerned that the copies of the key I had made might not work under some circumstances. They work just fine under normal conditions.

 

Google for "passlock passkey" and there's a lot of information. If I understood it, "Passkey" ('80s into the mid '90s I think) had the transponder in the key itself. "Passlock" (mid '90s to recently, at least) has an inner tumbler that activates a resistor, and hopefully can only be reached by a properly copied key. So, using a non-transpondered key in a "Passkey" system, or forcing the lock in a "Passlock" system, or trying to hotwire either, the computer will detect this and it won't start. (I believe on my diesel truck it will crank but not provide fuel.)

 

This subject gets a lot write-up for people who want to wire in a remote starter, or just want to be able to bypass it.

 

For 2004 and there-abouts, it's Passlock and we can make cheap copies of the keys. For Passkey I guess you have to pay to get a special key and have it programmed in. For 2007 and later I have no idea!!

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
