Key Fob
A tiny quality-of-life mod that turns every vehicle key in your inventory into a working key fob. Right-click a car key and use the Key Fob submenu to operate your vehicle from up to 50 tiles away.
Features
- Honk - a single short horn blip. Great for finding your car in a parking lot... or luring zombies exactly where you want them.
- Lock / Unlock - toggles all passenger doors (and the trunk) on the matching vehicle. Locking gives two quick chirps and arms the alarm; unlocking is silent and disarms/silences any active alarm.
- Panic ON / OFF - trigger or silence the vehicle's alarm remotely. The menu label automatically reflects whether the alarm is currently ringing (from any source - the fob, a smashed window, or a forced door).
- Break-in alarm - if someone smashes a window or tries to force a door on a locked, armed vehicle without the matching key, the alarm trips immediately and keeps looping until it is stopped legitimately.
- Auto re-arm - hitting Panic OFF while the doors are still locked silences the siren but re-arms the alarm, so the next intruder sets it off again.
- In-car override - a Disable Alarm slice appears in the vehicle radial (V) menu while a siren is active. Requires the same skill as hotwiring: Electrical 1 + Mechanics 2, or the Burglar trait.
- Cut / Fix Alarm - right-click Alarm in the Vehicle Mechanics window to Cut Alarm (permanently disconnect it) or Fix Alarm (reconnect a cut one). Cutting requires Electrical 1 + Mechanics 2 (or the Burglar trait); fixing requires Electrical 2 + Mechanics 3. While cut, the alarm cannot arm or trigger.
Stopping the alarm
A ringing break-in alarm will keep looping until one of the following happens:
- The owner hits Panic OFF on the fob (re-arms if the vehicle is still locked).
- The owner Unlocks the vehicle with the fob.
- The vehicle battery dies.
How it works
- Uses the vanilla horn, door-lock and alarm systems - so zombie attraction, multiplayer sync and sandbox settings all behave exactly like the base game.
- Only keys whose keyId matches a loaded vehicle will show the menu. No extra items to craft, no new loot tables.
- The submenu tooltip tells you how many tiles away the vehicle is, and greys out if it's out of range or not currently loaded.
- A broken window still lets you climb through normally - the alarm does not block entry, it just keeps screaming.
Compatibility
- Built for Project Zomboid B42.17.
- Single-player and multiplayer safe.
- Should play nicely with any other vehicle mod - nothing vanilla is overridden.
