Hyundai Key Replacement and Programming Made Simple
A modern Hyundai key is more than a piece of metal—it’s a coded device that talks to your car’s immobiliser. Here’s how we handle Hyundai key replacement and programming professionally and safely:
- Assess and verify
- We confirm ownership and your Hyundai’s VIN, model, year, and key type.
- We run quick diagnostics to check the immobiliser, ECU, and central locking status.
- Non-destructive vehicle entry
- Locked out? We use specialist lock-picking and air-wedge techniques to open your Hyundai without damage wherever possible.
- If a rare destructive method is the only safe option (for example due to damage or aftermarket security), we’ll explain clearly and get your approval first.
- Cut and code your key
- We cut laser or standard keys precisely to code.
- We program transponder chips and remote locking using dealer-level equipment.
- For smart keys and proximity systems, we perform anti-theft pairing and disable missing keys where required.
- For certain immobiliser types, we can carry out EEPROM or ECU/immobiliser programming to synchronise new keys securely.
- Test and handover
- We test door locking, boot release, start/stop, and remote functions.
- We provide guidance on using your new key/fob and any warranties applicable.
Need a spare? We can duplicate your working Hyundai key at the roadside to save you time later.

Hyundai Immobiliser and Key Types Explained
- Transponder keys
- A small chip in your key communicates with your Hyundai’s immobiliser. If the code matches, the car starts. We program replacement chips to your vehicle’s unique code.
- Remote flip keys
- Combine a transponder with remote central locking. We cut the blade and program both immobiliser and remote functions.
- Smart/proximity keys
- Keyless systems for push-to-start models (Tucson, Kona, Ioniq, Santa Fe). We code new smart keys, remove lost keys from the system, and ensure secure pairing to prevent unauthorised use.
- High-security/laser-cut keys
- Thicker, centre-grooved blades requiring precise cutting equipment—fully handled on our mobile units.
If your Hyundai reports “key not detected”, shows a key symbol on the dash, or the immobiliser light flashes, diagnostics will confirm whether the fault is the key, antenna, steering lock, or ECU—then we’ll fix accordingly.

FAQs: Hyundai Keys and Locks
Can you make a Hyundai key without the original?
Yes. We can create a new Hyundai key from your vehicle’s data. We cut the blade to code and program the transponder or smart key to your immobiliser, then remove any missing keys for security.
My Hyundai says “key not detected”. What should I do?
First, try a fresh key fob battery and hold the fob near the start button or steering column. If it still won’t start, the issue could be the key, antenna, or immobiliser. We can diagnose and provide on-site car key programming or repairs as needed.
Are your entry methods non-destructive?
Wherever possible, yes. We use specialist tools to unlock your Hyundai without damage. In rare cases where a component is already faulty or damaged, we’ll explain options and get your permission before proceeding.
How long does a Hyundai key replacement take?
Most replacements are completed at the roadside in one visit. Cutting and programming often takes 30–60 minutes once we’re on site, depending on model and system.
Do you offer warranties on Hyundai keys?
Yes. New Hyundai keys and our workmanship are covered by warranty. We’ll confirm the terms for your specific key type when quoting.
Is it cheaper than going to a Hyundai dealer?
In many cases, yes—especially when speed and convenience are considered. We come to you, often the same day, and handle everything on-site. For guidance on costs, see our overview of auto locksmith prices in Slough.
