Keys on some 1200s in some markets are matched: One key opens all doors as well as operates the ignition. In other markets there is a different key for the ignition. Also there are left-hand and right-hand keys that otherwise look identical.

Usage

1972 USA Owners manual (see pages 3-4 for key information):

Your Datsun is equipped with an ignition key warning buzzer... the key left in the switch, warning buzzer will warn you of being robbed.

Key Types

All Datsun 1200 used a VOSS double-sided (reversible) Nissan Motor key.

Early models with optional steering lock used a VOSS single-sided oval key for the ignition. So these 1200s used two keys:

The use of one-key-fits-all or two keys depended on the model, year and country:

USA 1971 sedan: 2 different keys
USA 1971 coupe: single key
USA 1972-1973: single key

OVAL KEYS

Early 1200 models with optional steering lock used an oval key for the steering column.

VOSS KEY00-00034/VH1000 single-sided

VOSS-type keys (KEY00-00034) were made by Kanto Seiki under license of VOSS of Germany. These were used starting around 1969. The former WASO type (KEY00-00028) were made by Kanto Seiki under license of WASO of Sweden. The only real difference is the length. The VOSS keys are shorter, which means WASO key won't fit in the VOSS cylinder. The longer VOSS keys should never be used in a WASO cylinder, as it may lock the steering incorrectly.

Nissan Motor Keys

All Datsun 1200 used VOSS Double-sided keys with the "Nissan Motor" text and "N" symbol. These fit the dash ignition switch, doors, boot and fuel filler lid locks. Also, later 1200s with steering lock used this key instead of the oval key.

VOSS KEY00-00035 double-sided

VOSS double-sided newer shape used in JDM (Sunny Truck) and SADM (Bakkie)

KEY00-00055? Left-hand $8.27 USD (not KEY00-00056 Right-hand)

Ignition Switch

3-position early JDM switch vs later 5-position switch:

Early JDM switches have "Garage" position.

5-position switch vs 4-position switch:

Note addition of ACC position.

1972 USA Owners manual (see page 11):

The "ACC" (accessories) position of the switch permits you to use all of the electrical accessories.

Portugal market:

Interruptor de ignićāo: Ingition switch
Desligado: Disconnected
Ligado: Connected
Arranque: Start

Standard Switch

Japan-market STD and DX models used a non-locking steering column. The ignition switch was mounted via bracket on the dash.

The key lock cylinder and ignition switch were one unit.

Early units had a 3-connector ignition switch. Later units had four connectors.

Steering Lock Switch

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

The body is cast 'KV-1'

'KV-1' cast at the saddle

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.

Dimensions

Length

Nissan keys come in various lengths. The original Datsun 1200 keys were the short length.

Short: ~31 mm groove length
- 2.0 inch overall
- Original 1200 reversible key length
Medium: ~38 mm groove length
- 2.4 inch overall
- Used by Datsuns & Nissans 1974-1981, Subaru, and Mazda Cosmo
Long: ~46 mm groove length
- 2.7 inch overall

Width

Width is 8.9 mm at the point where the grooves start.

Width of the teeth area is 7.1 mm

Center groove width: 2.3 mm
Outside groove width: about 1.0 mm minimum (some keys have it machined all the way out, that is to say a wider groove)

Right-Handed vs Left-Handed

The reversible key came in left-hand and right-hand versions. Datsun 1200 used only the left-hand style.

KEY00-00035 left groove
2nd groove is left of center groove

2nd groove is right of center groove

Aftermarket Keys

Two styles were used (center, right). The newer, longer one (left) will work, but is not the original style.

The little groove diagrams below the photos are for the keylock, so they are the reverse of the actual key.

WARNING: The first key is right-handed, while the second is left-handed. Each key comes either way. Be sure to purchase the correct one for your 1200 locks.

Interesting that some 1200s (newer utes?) came with two different keys originally. The 1971-1973 north american models came with single key for ignition, doors and trunk.

Oval Single-Sided Nissan Ignition Key

This is the earlier style for 1968-1971 Datsun, Mazda before the double-sided keys were used. This was used by 1971 USA 1200.

Key Code

When your key gets worn down too far, making a copy results in a poorly-working new key. Instead, have a new key cut from the original key code.

In Australia, the key cut number was stamped directly into the original keys
Additionally, the code may be stamped on the right-side door lock cylinder. Remove the door panel to get at the clip which holds the lock in.
- Not necessarily stamped on left-side door lock, nor trunk/boot lock, nor ignition lock

In USA, the key cut number was penciled onto the inside of the glove box door:

VF: for VOSS single-side KEY00-00034
- mine is marked "1", possibly to indicate my locks are a single-key system
VH: for older (pre-Datsun 1200) WASO KEY00-0028
Eng*/DOOR: 4-digit key code

Codes

- In the range of (M)5001-(M)6000 (or N) for reversible KEY00-00035/KEY00-00055
- range 4001-5000 is for mirror image keys (non-Datsun 1200)

Non-1200 Keys

Use only VOSS type for Datsun 1200

Single-Cut Keys

Do not confuse Datsun 1200 keys with these single-sided VOSS keys. They also had "Nissan Motor" text and "N" symbol, but were used by earlier models e.g. Datsun Roadster.
