Cheap Ford Sierra Ignition Switch

Yes, the Ford Sierra is a conventional petrol or diesel car and has a standard ignition switch fitted to every variant across the full production run from 1982 to 1993. It is a real and common part that breakers regularly remove from Sierra donor cars, so sourcing a used one is straightforward. Give your registration to the breaker so they can confirm the exact switch type for your car.

The Sierra ran in two main phases: the original 1982–1987 shape and the facelifted version introduced in 1987, which continued to the end of production in 1993. The ignition switch and barrel assembly can differ between these two phases, so a switch pulled from a pre-facelift car is not guaranteed to drop straight into a facelift car. Name the generation of your donor car to the breaker and confirm the part number matches before buying.

No, body style makes no difference to the ignition switch — the switch sits in the steering column and is shared across the saloon, hatchback, and estate variants. You do not need to seek out a switch from the same body style as your own car. Focus on the production phase and any column or lock-barrel differences rather than body style.

Trim level — whether L, GL, Ghia, or XR4i — does not affect which ignition switch you need, as the switch is a steering-column component common across the range. Similarly, the engine fitted (including the 2.0 Pinto, 2.9 V6, or diesel) does not change the switch specification. The one thing to be aware of is that some switches were sold with or without the lock barrel, so check with the breaker whether the part includes the barrel or just the electrical switch unit.

A 1985 XR4i is a pre-facelift car and your 1989 Ghia is a post-facelift model, so they sit either side of the 1987 revision and the switch may not be a direct fit. Trim — Ghia versus XR4i — is irrelevant to fitment, but the generation boundary is what matters here. Route this specific cross-generation swap to your breaker, giving them the registration of both cars so they can compare part numbers before you commit.

On many Sierra repairs the electrical switch unit behind the barrel wears out independently, but if your key is stiff or the lock is worn, replacing the full assembly including the barrel makes more sense. Used assemblies from breakers are widely available but will come with the original key, which means either having the barrel re-keyed by a locksmith or using two keys — one for the doors and one for the ignition. Discuss with the breaker whether they can supply just the switch unit or only the full assembly, as stock varies.
