Steering Lock

A locking steering column was a Datsun 1200 OPTION for early STD and DX models. It was standard equipment for USA 1200s, JDM GL and GX, and newer JDM 1200 pickups. The body of the steering lock is the same LHD vs RHD and early vs late. But the removable lock barrel, face plate and ignition switch differ. In particular, USA locks have a 2-wire connector for the key buzzer, while Japan locks say "Garage" on them.

Overview

In all 1200s -- both RHD and LHD -- the Steering Lock bolts to the right side of the steering column.

The body is cast 'KV-1'

A new lock comes with break-off bolts. Once tightened, the heads break off. To remove it requires tapping the bolts out slowly, or using a hacksaw to cut grooves in the lock.

Discussion: Steering lock bolts- how to tighten?

lock bolts - two Philips head, two security head

48700-M1010 - early style without ACC position

USA Left: 1972-1973 5-position, Right: 1971 4-position

USA Lock Comparison - No ACC position for 1971. It also uses a different ignition switch.

4-position
* Single-sided Key, differs from door keys
* Takes small one-lug ignition switch

5-position
* Double-sided Key, same as door key
* Takes large two-lug ignition switch

Short Type Lock

B210

JDM B210 steering lock looks similar to B110 version.
48700-H5000 and 48700-H5010

(racer135- my RHD 1978 B120 uses a similar black 5-position key/steering lock barrel as the USA 1972-1973 mentioned earlier, albeit with a small single-lug switch with 5 terminals as pictured above. It may be exactly the same as the one above but there aren't enough photos to confirm. Also, when the start position spring failed in the switch, I replaced it with the switch from a Mazda 1000 ute I had for parts, which just happened to have the exact same switch!)

USA B210 steering lock is totally different. Clamps at mid-barrel instead of end. 48700-H6200 pictured with Ignition Switch attached.

Ignition Switch

See main article: Ignition Switch

The actual electrical Ignition Switch for this type is removable, and bolts to the back of the key cylinder. In other words, the Ignition Switch is not strictly part of the Lock Cylinder, but connects to it. A rectangular wire connector from the dash harness attaches to the ignition switch.
