Question 1

How do I spot a fake locksmith before I get ripped off?

Accepted Answer

Three things give it away fast. First, they won't give you a firm price for your specific vehicle over the phone. Second, they show up and either can't do the work or suddenly need to "order something" and ask for a deposit. Third, the final invoice has line items that were never mentioned: a travel surcharge, a key-blank fee, an after-hours charge that applies at 2 in the afternoon.

For a simple mechanical key job on a 2002 Tahoe, the scope is clear before anyone touches the truck. Decode or pull the key code, cut the key, test it. A real locksmith tells you what that costs upfront and the number doesn't change when they pull out the bill.

Question 2

My 2002 Tahoe just uses a plain metal key, right? So why is replacement even a job?

Accepted Answer

It is simpler than a modern key, but it is still a job worth doing right. The key blade has to be cut precisely to match your lock cylinders. On a truck this old, there are usually three things working against a quick copy: the original key is worn down from years of use and won't copy accurately, the owner has lost all keys entirely and needs the code pulled or the lock decoded, or someone had a key made at a hardware store years ago that was already a generation off from the original cut.

Your 2002 Tahoe has no remote and no transponder to worry about. The key works the ignition, the door locks, and the glovebox. Get it cut correctly and you're done.

Question 3

What equipment do you use to cut keys for older vehicles like this?

Accepted Answer

For a 2002 Tahoe, the work is mechanical, not electronic. I use a professional automotive key cutter and either a code database or a lock decoder, depending on whether the owner has a key code on file or has lost all keys. Code cutting is faster when the code is available. Decoding the lock cylinder is the fallback, and it works just as well on vehicles this age. No programming tools, no laptop, no OBD connection needed for this one.

Question 4

All my keys are lost and I can't find the key code anywhere. Can you still make a key for my 2002 Tahoe?

Accepted Answer

Yes. This is one of the more common calls I get on trucks from this era. Owners bought them used, the previous owner handed over one worn key, and eventually that key gets lost or breaks.

When the code isn't available, I decode the lock. The door lock or ignition cylinder holds the cut information mechanically. I read it directly and cut to that. On a 20-plus-year-old truck, decoding the lock also lets me catch any wear or inconsistency that a blind code cut might miss. You end up with a key that actually works smoothly, not one that works on a good day and sticks on a cold morning.

Question 5

My key turns but the ignition feels stiff and sometimes it doesn't turn at all. Is that a key problem or something else?

Accepted Answer

On a 2002 Tahoe, this is usually the ignition cylinder itself, not the key. These trucks are known for worn ignition cylinders after this many years of use. A worn cylinder can get to a point where even a correctly cut key struggles to find the right position to turn.

Symptoms: key turns hard, key gets stuck, or the steering column lock releases inconsistently. If a new key doesn't fix it, the cylinder is the next conversation. That's a separate job from key cutting, but both are things I can handle on-site in Lemon Grove without a tow.
