If you're parked somewhere safe, such as at home, at work or in a car park, start with your breakdown cover provider if you have one. If you don't, call a mobile jump start or battery service, or a local garage for faults that aren't battery-related. Have your location, registration and symptoms ready before you call.
First, are you safe?
This guide is for cars that won't start somewhere safe, such as a driveway, street or car park. If you've broken down on a motorway or busy road, follow the Highway Code first. Our guide who do I call when the car won't start on the road covers that.
Who to call
- Your breakdown cover provider. Check your policy. Some only cover you at home if you added home-start cover.
- A mobile jump start service. This is useful when the battery is flat and you don't have cover. Jump Start Car offers a jump start from £70 and on-site battery replacement from £150, including the battery. Call 0333 567 1785.
- A garage or mobile mechanic. Use one when the battery isn't the problem, for example a jammed steering lock, fuel trouble or a starter motor fault, all of which the RAC lists as common no-start causes.
What to say when you call
- your exact location, including the car park level or bay if you're in one
- the make, model and registration
- what happens when you turn the key or press start: silence, clicking, slow cranking, or cranking that won't fire
- whether any warning lights are on
Quick checks while you wait
- If the key won't turn, the RAC suggests rocking the steering wheel gently while turning the key, as the steering lock may be jammed.
- Try a spare key if the central locking or immobiliser isn't responding. The fob battery may be flat (car key battery guide).
- Switch off all electrics to save what charge is left.
Frequently asked questions
Will breakdown cover help if my car won't start at home?
Only if your policy includes home-start cover. Check before you call.
Should I keep trying to start it?
No. The RAC advises not to crank for more than about 5 seconds at a time, as this can overheat the starter.
How much does a mobile jump start cost?
Jump Start Car's jump start costs from £70. Confirm the price when you call 0333 567 1785.
