LiveWire S2 Del Mar, Mulholland, Alpinista Key Replacement

Quick answerThe S2 bikes, the Del Mar, Mulholland and Alpinista, have no ignition key. Propulsion needs an assigned fob nearby or your PIN. A metal key is still supplied: LiveWire's S2 owner's manual says it is for the fork lock, and the same manual uses a key at the back of the bike: in the seat lock of the two-up seat, or in the fender cowl behind a solo seat. We cut and repair that mechanical key at the bike. Fobs are assigned by a LiveWire dealer.

Fob, PIN and the OFF/RUN switch

LiveWire's manual calls it keyless activation. With the security fob present you set the OFF/RUN switch to RUN. If the fob is missing or dead, the PIN disarms the security system instead. Carrying the fob away from a bike that is already on does not shut it down, but the display shows a NO FOB alert once the bike starts moving without it.

When parked and switched off with the fob out of range, the manual says the propulsion system and the OFF/RUN switch remain disabled. That is the immobilizer on an S2. Nothing about it involves the metal key.

What the metal key is for on an S2

The bike rides without it, so the metal key is easy to forget about. The manual gives it these jobs.

Fork lock: turn the fork to the full left position, insert the key, turn it to the right, and remove it. Turn it to the left to unlock, then check the bars move freely through their full range.
Two-up seat: the key turns clockwise in the seat lock and the seat lifts from the rear. The helmet locks are hooks under this seat, and latching and locking the seat secures the helmet.
Solo seat: the seat itself is held by two screws, not a lock. The helmet locks sit under the fender cowl behind it, and the cowl has a key cylinder: key in, turn clockwise, lift the cowl from the rear.

A locked fork means no propulsion

The fork lock on an S2 is tied into the electronics. The manual states that it has a sensor and that the system will not allow propulsion while the fork lock is engaged. A Del Mar that lights up normally but will not go may simply have its fork lock on.

This is the situation where a lost metal key actually strands an S2. With the fork locked and no key, the bike cannot be ridden and is awkward to wheel onto a truck. Opening the lock and cutting a key where the bike is parked avoids a recovery.

Things that catch S2 owners out

Fob batteries. The S2 manual does not ask you to buy a named cell. It tells you to fit a battery the same size as the one you take out, negative side up, so open the fob and read the cell before going to the store. It also recommends doing this every year.

The fob's serial number is on a reusable label in the fob packaging and inside the fob. Keep the label with your paperwork.

If the fork lock key starts to bind or needs wiggling, deal with it early. A key that snaps in a locked fork lock turns a small job into a larger one.

Lost key, lost fob or both

Lost metal key: we come to the bike, confirm ownership with your photo ID and the registration or title, and make a key for the fork lock and the seat or fender cowl lock. A broken key in the fork lock is extracted on the same visit.

Lost fob: use your PIN to ride and contact a LiveWire dealer, since replacement fobs are bought from and assigned by the dealer. Lost fob and no PIN: the bike needs the dealer, and we can still release a locked fork so it can be moved there.

Where to find the key code

Check the front pages of the owner's manual and the delivery paperwork for a recorded key number, and keep any tag that came on the key ring. The fob serial number is separate and is printed on the label in the fob packaging and inside the fob. If no key number was recorded, a LiveWire dealer can help with the VIN and proof of ownership, or the key can be made from the lock.

LiveWire S2 Del Mar, Mulholland, Alpinista key FAQ

Does the S2 Del Mar come with a key?

Yes. It does not start the bike, but LiveWire's manual says the key supplied with the motorcycle is for the fork lock, and a key also opens the two-up seat lock or the fender cowl behind a solo seat.

My S2 Mulholland turns on but will not enter propulsion. What should I check?

Check the fork lock first. The manual says the system will not allow propulsion while the fork lock is engaged. Then check that the fob is with you and its battery is good.

What battery does the S2 fob take?

LiveWire's S2 manual says to install a new battery of the same size as the one removed, negative side up, and to replace it every year. Read the marking on the old cell.

Can you make a new fob for my S2 Alpinista?

No. Fobs are assigned by a LiveWire dealer and only two can be assigned at a time. We handle the metal key, the fork lock and the seat or cowl lock.
