Ignition Repair Procedure

Symptom Diagnosis (What's Actually Broken?)

Key won't turn? Could be worn wafers inside cylinder or steering wheel lock engaged. Key turns but car won't start? Likely ignition switch (electrical component behind cylinder) or anti-theft system issue. Key stuck in ignition? Usually shift interlock—car must be in Park. We test with spare keys first—worn keys often false-diagnose as bad ignitions. Actual cylinder failure is less common than people think.

Cylinder Extraction & Housing Access (45-90 Minutes)

We remove steering column covers (3-8 screws typically), disconnect electrical connectors, release shear bolts on cylinder housing. Modern cars have anti-theft shear bolts designed to break during installation—we drill them out with left-hand bits. Older GM ignitions (pre-2010) often just need the lock plate compressed and retaining ring removed. European cars (BMW, Mercedes, VW) require dash panel removal—much more labor-intensive, hence higher cost ($400-700 vs. $200-400 domestic).

OEM vs. Aftermarket Replacement Decision

OEM (dealer parts): Higher cost ($250-600) but guaranteed fit and includes correct transponder. Aftermarket: Half the price but may not include chip—we'd need to transfer yours. Older vehicles (pre-2000) with simple mechanical cylinders use aftermarket no problem. Newer vehicles (2005+) with integrated immobilizer chips often require OEM to avoid programming headaches. We source parts same-day from local suppliers—no waiting for dealer backorders.

Transponder Programming & Anti-Theft Relearn

After installing new cylinder, car's computer must relearn security codes. Some vehicles enter relearn mode automatically when you turn key (GM PassKey systems). Others need forced relearn: 10-minute key-on sequence or OBDII programmer ($100-200 dealer fee, we include it). This step overlaps with our key fob programming service for vehicles with push-button start. Chrysler/Dodge vehicles often require PIN code from dealer—if you don't have it, we extract from BCM using specialized software. Relearn failures trigger security light and no-start—we guarantee functional relearn or no charge.
