Frequently Asked Questions
Will This Lock Cylinder Work With Aftermarket Immobilizer Systems?
No; it generally lacks built-in transponder electronics, so aftermarket compatibility depends on immobilizer integration method used. Installation often requires an external bypass or adapter for systems needing transponder communication to achieve full immobilizer integration.
Are Original Keys Programmable or Unique to Dorman Unit?
Original keys are not programmable to the Dorman unit; they remain unique. Like two rivers meeting, key compatibility depends on cut and tumblers, while programming options relate to immobilizer or transponder systems, not the metal cylinder itself.
Does the Cylinder Include a Dust Boot or Weather Seal?
No, the cylinder does not include a dust boot or weather seal; the Dorman 924-866 ships as the lock cylinder with two keys, so the purchaser should obtain an external dust boot or weather seal if needed for their application.
Can the Cylinder Be Re-Keyed to Match Other Vehicle Locks?
Yes. He notes re keying options exist: a locksmith can rekey the cylinder to match other vehicle locks, but lock compatibility depends on keyway and tumblers; verifying fitment and key profile before rekeying is advised.
Is There a Lifetime Warranty or Roadside Assistance Coverage?
No, there is no lifetime warranty or roadside assistance coverage; warranty details note standard Amazon return/warranty policies, and assistance options are limited to seller/customer service and manufacturer support channels for claims and technical help.
