Royal Enfield Bullet 500 and Classic 500 Key Replacement

Quick answerThe fuel-injected Bullet 500 and Classic 500 are fully mechanical where keys are concerned. Royal Enfield's manuals say one key is common for the ignition, petrol tank cap, steering lock, battery cover and tool boxes, and they describe no immobilizer. A lost key is made by cutting to the existing locks, and because these bikes have five or more keyed locks, checking the new key in every one of them is part of the job.

Royal Enfield Bullet 500 and Classic 500 key quick facts

The Classic 500 and Bullet 500 manuals say the key is common for ignition, petrol tank cap, steering lock, battery cover and tool boxes.
The owner data page at the front of both manuals has a Key No. line next to the frame and engine numbers.
The battery sits behind a keyed battery cover, so a lost key also blocks battery access.
The manuals list the steering lock as its own control: turn clockwise to lock, anticlockwise to unlock, with the handlebar at the extreme left.
The tool kit is kept in the left side electrical and tool box, which is opened with the key.

One key for a lot of locks

Modern bikes usually have three keyed locks: ignition, fuel cap and seat. The 500 singles have more, because the side boxes that give the bike its shape are all lockable. The note in both manuals reads: key is common for ignition, petrol tank cap, steering lock, battery cover and tool boxes. The parts diagrams label an electrical and tool box on the left, an air filter box, a utility box and a separate battery cover.

A second note explains how the key behaves: it can be removed only in the locked position from the fuel tank, filter box and electrical box locks, and in the OFF position from the ignition switch. If a key seems stuck in a side box, the lock is almost always not fully home.

Steering lock and ignition

The controls page lists the steering lock separately from the ignition switch, with its own directions: turn clockwise to lock and anticlockwise to unlock. The manuals add that you should turn the handlebar to the extreme left before attempting to lock the steering. On a bike this age the steering lock is often the stiffest lock on the machine because it is used least. If it has not been turned in years, do not make the first attempt with your only key.

The battery cover lock

The battery maintenance section shows why the key matters beyond starting. To remove the battery you insert the key into the battery cover lock, turn it anticlockwise and hold while the cover comes away. Refitting is a turn-and-push action with the key before it is released. A fuel-injected bike that has been sitting often has a flat battery as well, and on these models the key has to come first.

Key numbers and matched lock sets

Both manuals open with an owner data page for the dealer to complete. Alongside engine number, frame number and battery details there is a line marked Key No. If your manual was filled in at delivery, that number is the fastest route to a new key cut to the original pattern, so look there before anything else.

The locks are supplied as a matched common-key set, which is why one key runs the bike from new. On an older bike it is not unusual to find that a single lock, such as a tool box lock, has been replaced, and that lock then has its own key. A locksmith can rekey an odd lock to match the rest so you are back to one key.

Lost key visit for a 500 single

We check photo ID and the registration or title, then make a key from the bike's own locks, or from the Key No. if you have it. Unless an aftermarket alarm or immobilizer has been fitted, there is nothing to program. The new key is then tried in the ignition, steering lock, fuel cap, battery cover and each side box, and we tell you about any lock that does not match. Worn locks on older bikes sometimes need cleaning or repair before a new key works smoothly, and that can be done in the same visit.

Where to find the key code

Check the owner data page at the front of the owner's manual, which has a Key No. line for the dealer to fill in next to the frame and engine numbers. If it is blank, the key is made from the locks on the bike.

Royal Enfield Bullet 500 and Classic 500 key FAQ

How many locks does one key open on a Classic 500?

The manual says the key is common for the ignition, petrol tank cap, steering lock, battery cover and tool boxes. On a bike with original locks, that is every lock on the machine.

Does a Bullet 500 have an immobilizer?

No immobilizer is described in Royal Enfield's manuals for the Bullet 500 or Classic 500. The key is a plain cut key.

One of my Classic 500 side boxes takes a different key. Can that be fixed?

Yes. That usually means the lock was replaced on its own at some point. It can be rekeyed to match the ignition key so one key works everything again.

Where is the key number on a Bullet 500?

The owner data page at the front of the manual has a Key No. line, if the selling dealer filled it in. Check there and on any tag that came with the keys.
