Steps

  1. Check that your key fob has a remote start button. It usually looks like a circular arrow, and on some cars you must press lock first to arm it.

  2. Stand within about 30 metres of the car, press the lock button once, then press and hold the remote start button for three to five seconds.

  3. Watch for the parking lights to flash or the horn to beep. That confirms the engine started. If nothing happens, press the buttons again more slowly.

  4. Let the engine idle for five to ten minutes in cold weather. Modern cars warm up faster when driven gently than when left sitting.

  5. The doors with the button, get in, put your foot on the brake and press the start button to take over the car.

  6. To lock up, press the lock button once. Most cars flash the indicators once, and some beep the horn to confirm the doors are locked.

  7. Press lock twice within a few seconds on many fobs to deadlock the car or set the alarm. Check your owner's manual for what your car does.

  8. If the fob stops working, replace its battery or pull out the hidden metal key to the driver's door by hand.

Tips and common mistakes

Never warm up a car in a closed garage, because the exhaust fumes can kill you.

Do not leave the engine running with the fob inside where it is illegal or easy to steal.

Long idling wastes fuel and does not help the engine, so keep warm-up short.

Keep the fob away from phones, coins and metal, which can block the signal.

Questions

How long should I warm up my car in cold weather?

Five to ten minutes is plenty for most cars. Below freezing, a few extra minutes helps clear the windows, but driving gently warms the engine faster than idling.

Why will my key fob not remote start the car?

Common causes are a weak fob battery, being too far away, an open door or bonnet, or low fuel. Try a new battery and stand closer before assuming a fault.

Can I lock the doors while the engine is running?

On most cars with remote start, yes. Press lock on the fob and the doors lock while the engine keeps running. The car usually shuts off when you open the door to drive.
