Smart Cars have a very clever built in system that tells you when the key fob battery is running low and requires changing. When unlocking the car the indicators will flash nine times – and the car will unlock.

The problem is, most customers don’t know about this nifty little feature. Most people also don’t realise that the vehicle’s immobiliser is controlled by the remote. Once the key fob’s battery completely runs out, the remote will lose sync with the vehicle and you will no longer be able to start the car –even if you change the battery!

So what’s the solution to this problem?

Well, the first thing to try is to change the key fob’s battery. There’s a chance that your dead battery still has enough life in it to stay synced to your vehicle. I will list the types of battery needed for each model at the end of this article.

If the above doesn’t work then it’s time to get your key re-synced to your vehicle. This requires expensive diagnostic equipment and needs to be done by a professional. Fortunately Autolox can do this for you quickly and cheaply. We come to you and will have your Smart Car back on the road the very same day.

So if you are in this situation – please just give me a ring and speak to an experienced locksmith on 07776 222 722.

    I took your advice on this as my 7 year old smart car that i bought a week ago started flashing 9 times when locking the car. I tried the spare key which i had just put a new battery in and that flashed the indicator lamps 3 times ,but the next time i tried to lock it the 9 times flashing started again, Any help with this would be much appreciated. now sent off for another battery for the key from ebay
