Ignition Lock Repair: getting ready

Turning the key used to take one smooth motion. Lately it grinds partway through, sometimes needing a second attempt, and yesterday it stopped reaching start altogether. The key itself looks the same as always; something inside the ignition has changed instead.

Worth answering before the call

Where is the vehicle parked right now? Does the key insert, turn partway, or not turn at all? Has this ignition been serviced or replaced before?

What is actually different between ignition lock repair and dealer key programming?

The lock cylinder is mechanical: a key physically turns it through accessory, on and start. The immobilizer and transponder system is electronic: it recognises a chip inside the key before allowing the engine to run. A locksmith services or replaces the physical cylinder; programming a chip to the vehicle's electronic system is separate work that a suitably equipped automotive locksmith, a dealer, or an automotive electrical specialist can handle.

I just bought a used vehicle with one worn key. What should I expect?

A single worn key is a common starting point after buying used, and the visit usually has two parts: reading the existing wafers so a crisp new key can be cut, and deciding whether the barrel itself needs a service given whatever wear the previous owner's key left behind. Bringing whatever paperwork came with the sale helps confirm ownership before any work begins.
