Motorcycle Key and Lock Work for Repair Shops

Quick answerA general motorcycle shop can sublet key, ignition and lock work to a mobile motorcycle locksmith who does it at your shop while the bike is on your lift. In California the Automotive Repair Act covers motorcycles, so sublet work goes on the customer's written estimate with their consent, and your shop remains responsible for it. Send the year, make, model, VIN, what keys exist and what the fault is, and have the customer's ID and registration details ready if a key has to be made from scratch.

Jobs a shop may prefer to send out

Lock and key work needs code machines, key blanks for dozens of makes, wafer kits and immobilizer programming equipment that a general shop has little reason to own. The typical cases are below.

Customer has lost every key and the bike was towed to you
Bike came in for other work with one worn key that barely turns the ignition
Ignition cylinder is worn, sticking, or was forced in a theft attempt
Replacement ignition switch, fuel cap or seat lock fitted, and the customer wants one key for everything
Key broken off in the ignition, fuel cap or seat lock
Seat or fuel cap will not open and it is blocking your access to the battery or tank
Immobilizer bike needs a key added or replaced after an ignition, ECU or lock set change
Used lock set or switch from a breaker that needs keys made to fit

Lock fault or electrical fault: who does what

An ignition switch has a lock cylinder at the front and electrical contacts behind it. A key that will not turn, sticks or pulls out in ON is a cylinder or key problem and is locksmith work. A dash that flickers when the key is moved or an engine that cuts out is the electrical half or its wiring, which is your diagnosis. NHTSA recalls show how the electrical side fails: Yamaha recalled 2006 to 2009 FJR1300 models because wiring inside the ignition switch could disconnect and stall the engine, and Harley-Davidson recalled 2014.5 to 2016 Dyna Low Rider models because vibration could internally damage the switch. A recall check on the VIN is worth doing before quoting a customer for a switch.

The two trades meet when a switch is replaced. A new switch normally comes with its own keys. The cylinder can often be keyed to the customer's original key, or the other locks matched to the new one, and on an immobilizer bike the keys also have to be recognized by the bike. Honda's manual for HISS models, which are uncommon among US-market bikes, is a useful illustration: a duplicate has to be registered using an existing key, the key tag and the motorcycle, and if all keys and the tag are lost the PGM-FI unit or ignition control module has to be replaced.

California rules when you sublet

The Automotive Repair Act definition of a motor vehicle expressly includes motorcycles, and it defines an automotive repair dealer to include a business that collects for repair work that is referred or subcontracted to someone else. Business and Professions Code 9884.9 then sets three points that apply to sublet lock work. The written estimate must include a statement of any work that will be done by someone other than the dealer or its employees. Sublet work needs the customer's consent, unless the customer cannot reasonably be notified. And the dealer remains responsible for the sublet work in the same manner as if its own employees had done it.

In practice that points to listing the key or lock work on the estimate as sublet, with the customer's authorization as for any added work, and keeping the locksmith's invoice with the repair order. This is general information, not legal advice. The Bureau of Automotive Repair is the authority on how it applies to your shop.

Paperwork when a key is made from scratch

California Penal Code 466.6 requires anyone who makes a vehicle ignition key other than by duplicating an existing key to record the identity and ID number of the person the key is made for, the vehicle's registration details and VIN, and that person's signature, on a work order kept for two years. Business and Professions Code 6980.55 has a matching record requirement for locksmiths, and our proof of ownership guide lists the full record.

The bike belongs to your customer, so the cleanest arrangement is for the registered owner to be the person on the work order. Expect to be asked for the items below. A straight duplicate from a working key is not covered by the work order rule.

The customer's photo ID and registration or title, or the customer present to sign
Your repair order showing the customer's name and the VIN
If the customer cannot attend: their written authorization and a copy of their ID, with a named person at your shop signing for the key
The bike on site, so the VIN on the frame can be checked against the paperwork

What to send when you call

A complete first message usually means the right blanks and parts arrive on the first visit.

Year, make, exact model and VIN
How many keys exist and whether they work every lock
Any key number tag, code card, PIN or master key the customer has
Whether the bike has a chip key or keyless fob, and what the immobilizer light does with the key on
The fault in plain terms: will not turn, turns but no power, stuck, broken off, forced
Whether the ignition or any lock has been removed, replaced or disassembled already, and where the parts came from
Photos of the key, the face of the ignition and any damage

How a visit fits around your work

We are mobile and work only on motorcycles and scooters in San Diego County, Ventura County, Santa Barbara and Goleta. The work is done at your shop, so the bike does not have to be moved. If the tank, seat or fairing is already off for your own job, leave it off, since access to the ignition or lock is often easier. For immobilizer programming the bike needs a healthy, connected battery. When the job is finished, every key is tested in every lock with you, and you get the keys, any key number and an invoice to attach to your repair order.

Quick questions

Does the customer have to be at the shop?

Not for a duplicate from a working key. For a key made from a code or from the lock, the law requires a named person's ID details and signature on the work order, so arrange the customer's ID and authorization in advance.

We fitted a used ignition switch with no key. Can keys be made for it?

Usually yes, by decoding the cylinder. On an immobilizer bike the key must also be registered to the bike, which depends on the make and on what original keys or codes are available.

Do we have to tell the customer the work was sublet?

Business and Professions Code 9884.9 says the written estimate must state any work done by someone other than the dealer or its employees and that sublet work needs the customer's consent, with a narrow exception when the customer cannot reasonably be notified.

Can you diagnose a no-start for us?

We can tell you whether the key, the lock cylinder or the immobilizer key recognition is at fault. Wiring, charging and engine management diagnosis stays with your shop.
