Smart Cars are equipped with an ingenious system designed to alert you when the key fob battery is running low. This user-friendly feature ensures you’re never caught off guard by a dead key fob. When the battery begins to lose power, you’ll notice the car’s indicators flashing nine times upon unlocking. This clear and unmistakable signal is your prompt to replace the battery, helping you avoid potential inconvenience and ensuring your vehicle’s immobiliser system remains fully functional. By proactively addressing this alert, you can maintain seamless access and operation of your Smart Car, highlighting the brand’s commitment to combining advanced technology with everyday practicality.

Common Problem:

Many owners are unaware of this feature and don’t realise that the vehicle’s immobiliser is controlled by the remote. When the key fob battery dies completely, the remote loses sync with the vehicle, preventing the car from starting even after the battery is replaced.

Solution:

Step 1: Change the Key Fob Battery Firstly, try changing the key fob battery. There’s a chance that even a nearly dead battery has enough power to keep the remote synced to your vehicle. Here are the types of batteries needed for each Smart Car model:

• Early 600cc (One button key): 2x CR2016
• Fortwo 600cc: CR1225
• Fortwo 700cc: CR1225
• Fortwo 800cc: CR1225
• Fortwo 999cc: CR2016
• Forfour: CR2016
• Roadster: CR1225
• Crossblade: CR1225

Step 2: Re-sync Your Key Fob If changing the battery doesn’t work, the key fob needs to be re-synced to the vehicle. This requires specialised diagnostic equipment and should be done by a professional.
