Ignition lock

An ignition lock is the key-operated part of a car's ignition that stops the engine starting until the right key goes in. Inside sits the ignition lock cylinder, also called the ignition barrel, which turns with the key and works the ignition switch to power up and crank the engine. It sits on the steering column or dashboard.If the key will not turn, the steering lock has usually engaged, so rock the wheel while turning the key; if it still sticks, the cylinder is worn. Years of turning wear the tumblers, a bent key strains them, and a heavy keyring drags on the cylinder, so a worn lock usually needs a full ignition lock replacement, not a repair. Signs to watch for:

• The key sticking, jamming, or needing a wiggle to turn.
• The key turning but the car failing to crank.
• A key that will not go in or pull out cleanly.
• The lock feeling loose or spinning freely.

A worn car ignition lock can leave you stranded if the key finally refuses to turn, so sort it at the first sign of sticking. A used ignition lock is the cheap fix, though the right one is buried among breaker listings.Parthunt24 lists used ignition lock offers from marketplaces like ProxyParts, Ovoko, eBay, and TotalParts, so you can compare 1223 offers on price and condition in one view, then click through only once one fits.

An ignition lock is tied to your car's key and anti-theft system, so the part number and key type matter far more than the look. Get the make, model, year, and OEM part number right first, then the key type (mechanical, transponder, or smart key), the immobiliser coding, the steering column, the switch type, and the connector. On most cars since the late 1990s the lock or its chip must be coded to the immobiliser, or the car will not start, so get this step right.Enter your car in the Parthunt24 filters, and the list shows only the locks that fit. Open a listing and it opens that seller's page, Ovoko or eBay for example, to confirm the details and pay.

• Vehicle compatibility: Match make, model, year, and OEM part number.
• OEM part number: The most reliable way to ensure correct fitment.
• Key type: Mechanical key, transponder key, or smart-key system.
• Immobiliser compatibility: Must match the car’s anti-theft system and chip coding.
• Steering column design: Column shape and mounting points must match.
• Ignition switch type: Separate switch or an integrated ignition lock module.
• Connector type: The plug must match the vehicle wiring.
• Key blade profile: The key cut must correspond to the lock cylinder.
• Number of pins/positions: ACC, ON, and START positions must match the system.
• Locking mechanism type: Spring-loaded, electronic, or anti-theft reinforced.
• Door lock integration: Some cars use one key for the doors and ignition.
• Condition: Check for worn tumblers, a jammed cylinder, or a damaged housing.

On a used lock, the photos and the listing description matter most, since a worn cylinder or missing key is easy to miss even in a tidy photo. A used ignition lock usually comes keyed to a different key, so expect its key to be included or to have it re-keyed to match your car. Work through these:

• Photos: the cylinder face, the key if included, the connector, and the housing.
• Seller reputation: a locksmith or auto-electrician with a strong recent record.
• Compatibility info: the OEM number and key type lined up with your car.
• Included components: the cylinder alone, or with the key, switch, and housing?
• Condition description: any worn tumblers, a sticky cylinder, or a missing key noted.
• Testing/inspection: a note the key turns smoothly through every position.
• Warranty and returns: a clear policy if the key is missing or it will not turn.
• Shipping and packaging: boxed so the cylinder and key cannot be bent or lost.
• Documentation: the donor car and whether the key and chip come with it.

If the lock and key check out, click through and order it on the seller’s marketplace.

An ignition lock price rides on the car, the key technology, and how common the lock is, not one fixed figure. A mechanical lock for a common car is the cheap end, a rare or anti-theft barrel is dearest, and transponder or smart-key units sit between the two. On Parthunt24, an ignition lock starts from as little as 5.00.What decides one ignition lock price over another:

• Key technology: a transponder or smart key lifts the ignition lock price over a plain mechanical one.
• Rarity: a lock for an unusual model is hard to come by.
• Completeness: a lock that comes with its key and coded chip is worth more.
• Condition: a smooth, unworn cylinder with a clean key holds its value.

With the ignition lock prices side by side on Parthunt24, the cheapest that fits stands out without any effort on your part.

A no-start or a key that will not turn is not always the lock, so check the parts that share the job first. Often the cause is a worn key or the engaged steering lock, not the cylinder itself. It’s worth checking these parts too:

• Engine control module (ECU): holds the immobiliser that must recognise the key before the engine starts.
• Wiring harness: the ignition switch feeds through it, so a broken wire can mimic a dead lock.
• Car battery: a flat battery is the usual culprit when a car will not crank.
• Steering wheel lock: engages to block the wheel and jam the key.
• Ignition key: a worn or bent key may not turn.
• Ignition lock cable: a snapped one stops the lock working.
• Immobiliser antenna: reads the key chip to allow starting.
• Immobiliser control module: clears the key code, or the engine stays dead.
