Few things are more frustrating than turning the key and getting nothing. In busy towns and cities, where short journeys, cold mornings and stop-start driving are hard on batteries, a car that won't start is very often a battery problem, but not always. This guide walks through the quick checks you can do yourself, what the different sounds mean, and the point at which it's better to call someone.
Check the obvious things first
Before assuming the battery is flat, check that the gearbox is in park or neutral, the clutch is pressed on a manual, and the key fob has not lost power. Some push-button cars will refuse to start if the fob battery is weak; holding it against the start button can help.
Listen to what the car does
A fast clicking noise or a slow, dragging crank usually means the battery has run low. A single loud click can be a battery terminal or starter fault. Complete silence with dim or no dashboard lights often points to a very flat battery or a disconnected terminal.
Look at the dashboard
If the dashboard lights flicker or dim when you turn the key, the battery is the most likely cause. If the lights are bright but the engine will not crank, the fault is more likely the starter motor or a safety interlock.
When a jump start will work
A jump start works when the battery has been drained by lights left on, short journeys, cold weather or age. It will not help with a failed starter, an empty fuel tank or a blocked fuel line.
When to call us
If you can hear the car trying to turn over, or the dashboard is dim, a jump start is worth trying first. If you are in a spot that is unsafe, or the car makes grinding noises, call and we can advise whether this is a jump start or a recovery job.
Common questions
Why won't my car start but the lights work?
If the lights are bright but the engine won't turn, the problem is more likely the starter motor, a security immobiliser or a loose connection than a flat battery. A dim dashboard usually points to a weak battery.
Can a flat battery fix itself?
Not really. A battery that has drained may show a little life after resting, but it won't hold a charge reliably. Jump-starting and then driving, followed by a battery test, is the sensible route.
How long does a jump start take?
Once our technician is with you, most jump starts take 10–15 minutes including a quick check of the battery and charging.
When should I call recovery instead of a jump start?
If the car cranks but won't fire, you smell fuel, there is grinding or a burning smell, or the car has stalled in an unsafe place, a recovery truck is usually the right call.
