Hyundai cars in Singapore
Hyundai's Avante, Ioniq and Kona are common in Singapore, including many private-hire and electric models. We work on Hyundai models including the Avante, Elantra, Ioniq, Kona, Tucson and Santa Fe.
A typical Hyundai call
This is the kind of Hyundai call we often get: A private-hire driver with an older Avante has a remote flip key that only works when it's held right next to the door. The battery is weak and the driver can't risk a dead key mid-shift. We sort out a cloned spare so there's always a backup in the car bag.
What's different about Hyundai keys
Newer Hyundais may also support a digital key on a phone or card. A fob is still the backup most owners rely on, especially private-hire drivers who can't afford downtime. Hyundais use remote flip keys on many models and smart keys with push-button start on others. Smart keys usually contain a mechanical key for emergencies.
Hyundai key fob battery dead? How to get in and start
- Get in: A metal key hides in the back of most Hyundai smart keys; a press of the release frees it for the driver's door.
- Start the car: Use the fob itself as your finger: push the ENGINE START/STOP button with the end of the smart key. The car reads it at close range even with a weak battery.
Details vary by year, so check your manual. Still stuck? Call us. Key locked inside instead? See keys locked in the car.
Hyundai key fob battery replacement
Most Hyundai fobs take a 3V coin cell (often CR2032 or CR2025): copy the type printed on the old one and fit the new cell the same way up. Not working after the swap? See key fob not working after a battery change; if the backup start above works, the Hyundai fob itself is fine.
Hyundai spare key
Down to one Hyundai key? We clone Hyundai remote key fobs from a working key, after checking your NRIC against the log card. We don't clone smart (keyless) keys. Cloning costs S$100–S$1,000 depending on the car, so WhatsApp 9224 9224 the model, year and a key photo to confirm first.
Tips for Hyundai owners
- Private-hire drivers: keep a spare fob so a lost key doesn't cost you a day's work.
- Slide out the mechanical key and find the driver's door keyhole now.
- Change the fob battery when the remote range drops.
