When And Why It Fails
Ignition housings and barrels typically fail due to mechanical wear of tumblers, repeated key stress, the accumulation of dirt and debris, corrosion, or damaged keys. Symptoms include a key that won’t turn, intermittent starting issues, or a loose feel in the barrel. Electrical contact wear can lead to poor ignition switching or no-start conditions.
Replacement Guide
Replacement is straightforward for experienced technicians and competent DIYers:
- Disconnect the vehicle battery to avoid short circuits.
- Remove the steering column covers (upper and lower) to access the ignition housing.
- Disconnect the electrical connector and remove any retaining screws or clips holding the ignition housing in place.
- Withdraw the old ignition housing or barrel and install the new unit, ensuring the mechanical alignment and electrical connector are secure.
- Reassemble the steering column covers, reconnect the battery, and test key operation and engine start.
Note: Some vehicles may require immobilizer or transponder key verification/programming after replacement. If your vehicle uses a transponder key, consult a qualified locksmith or dealer for programming requirements.
