Hotwiring and starting a car in Project Zomboid

Every car has its own key, and only that key starts it. House keys and keys from other cars do nothing. The key works from your inventory or from a key ring you carry. If the key is already in the ignition, you can start the car without picking it up.

No guide checked for this page publishes key spawn odds, so the table gives a search order. Many cars have no key nearby.

How often keys appear as loot and how often cars are locked are both sandbox settings. The Vehicle Easy Use setting removes the key system completely: every car opens and starts without one.

Try every door before you break anything. If all of them are locked and you have no key, right-click the car or use the vehicle menu from outside and smash a window, then get in through that door. Breaking glass is loud, and it can set off the car alarm if the car has one. No source gives an alarm percentage.

Guides advise breaking the glass with a tool or weapon in your hands instead of a bare arm. A quieter route, if your Mechanics level allows it, is to uninstall the window from the car's mechanics menu (one source).

Opinion Break a rear window or the front passenger window, not the driver's. A broken window stays broken until you fit a new one, and a zombie reaching through an open frame is least dangerous when it is not next to your seat. Climb in, then press the switch seat key (Z by default, see controls) to move to the driver seat.

Sit in the driver seat, open the vehicle radial menu (V by default) and pick Hotwire Engine. The option only appears when you have no matching key, there is no key in the ignition, the engine is off and the car is not already hotwired.

No source checked for this page gives the success percentage. They agree that higher Electrical helps and that cars with a better engine are harder to hotwire. Every attempt makes a sound. A failed attempt can trigger the alarm, and higher Electrical lowers that risk. Two guides also say a failed attempt can leave the wiring broken; a third says failure does not damage the car. Treat that point as unconfirmed.

To reach the skill gate, take electronics apart with a screwdriver for Electrical and uninstall and reinstall parts on wrecks for Mechanics. Burglar is covered under traits and occupations.

Hotwiring removes the key requirement and nothing else. After it succeeds, you start the engine the normal way, with W or the dashboard ignition, and so can anyone else. In multiplayer that means any player can drive off in a hotwired car.

• It does not fix a dead car. You still need fuel, a charged battery and an engine in working condition.
• It does not create a key. No source checked for this page describes any way to make or copy a car key in unmodded Build 42, so assume a car without a key stays keyless.
• Locks: we could not confirm from any Build 42 source how locking the doors and trunk behaves on a hotwired car with no key. Test it on your car before relying on it.

Opinion A key is still better than wires. It carries no alarm risk, and other players cannot simply drive off in the car.

A hotwire attempt costs noise, so inspect the car first. From outside, open the hood or the mechanics menu to read the condition of each part. From the driver seat, the dashboard shows the fuel gauge, the battery light and the engine light.

There is no jump-start in the unmodded game. One guide states plainly that jumper cables and push-starting exist only in mods. Two fixes remain.

1. Swap. Take a charged battery out of another car and install it. The engine must be off. One guide says the job needs a screwdriver and no Mechanics level (one source).
2. Charge. Put a car battery charger on a powered tile, connect the battery and switch it on. Power can come from the grid or a running generator. One guide gives roughly 6 game hours from empty to full (one source). The charger restores charge, not condition, and has no crafting recipe, so you have to find one in auto shops, gas stations or garages.

A running engine slowly recharges its own battery, so a car that starts at all will top itself up as you drive. The full repair side is on the vehicles page.

Opinion Take the first car that has a key, some fuel and a working engine, whatever the model. Swap up later.

Opinion When you do have a choice, look for these in order:

• Standard class. Standard cars are the most common, so parts are easy to find, and their engines can be repaired at a lower Mechanics level than heavy-duty or sport engines. One Build 42.22 list names the Chevalier Nyala as the car to look for first because it spawns in the most places and has four seats and a 55 trunk (one source).
• Quiet engine. Engine noise pulls zombies along your whole route. Heavy-duty trucks and vans carry more but are louder and use more fuel. See stealth.
• Easier to hotwire. Because engine quality counts against the hotwire roll, an ordinary family car is a better target than a sports car.
