Truck: 2004 Silverado 4x4 EC 133,000 Miles, No CEL's or other warning lights.

Problem: When the keys are removed from the ignition the warning chimes still sound and the truck thinks the keys are still in the ignition.

I'm fairly handy, any advice where to start would be most appreciated.

key sense in the cylinder is more than likely sticking. You could use some key lube like some dry graphite and see if that works.

  I'm having similar issues, though, mine is more like a 50% success rate. I've cleared cache, restarted both phone and infotainment system, and forgot and repaired phone. Mine does work with a cable, but frustratingly very hit or miss with Bluetooth. It's a 2025 and worked reliably until about six weeks ago. Suggestions greatly appreciated.

  You should be evaluating enough comparable trucks to know if one sounds different than the others - if you can't tell something is amiss by ear, it's probably fine. Further evaluate enough trucks so that you can determine what 'normal' looks, sounds and feels like. Even if this is the first truck you're looking at and want to buy, go look at several more (regardless of whether you intend to buy them). Insist on taking the vehicle to be evaluated, spend some time looking ALL OVER IT, look for overspray where it shouldn't be, paint damaged on bolt heads that are not normally removed. Check for rust, missing fasteners, non-factory style fasteners, suspiciously new parts especially on non-wear items. Check for leaks, check fluid conditions and level (dirty isn't the worst thing in the world but exceptionally low is). Ignore tire shine and plastic dressing that makes an engine 'shiny'. Beware of heavily fragranced interiors to mask odd odors that could hide potential mold from a leaky rear window. Carfax is barely worth the paper it printed on. DO NOT trust it, a vehicle can be wrecked, fixed by a bunch of drunk hillbillies in their cousin's backyard and still have a clean Carfax. I can meticulously maintain my vehicle at home with top quality parts, materials and methods, the Carfax won't show a thing. Taking it to a shop to have a teenager working afterschool (an inexperienced mechanic) evaluate it is a waste of time. Lastly, a good, well taken care of truck will present itself as such, it would be generally comparable to a new truck. An uncared-for truck will show it, dents, scratches, seat stains, paint swirls, tears, scuffs, marks, rattles, vibrations, clunks, miss matched tires, etc...

  If you suspect an engine swap or similar modification to the front accessory drive... Maybe try spending some time plugging in different make/models/years that utilized the same engine (prime donor vehicles or swap candidates), vans, full-size cars (Impala, Roadmaster), 4x4 trucks to get a collection of pump and brackets that are similar along with their associated part numbers; take that collection of part numbers to the parts store to compare. Another Okie.
