WHAT THE SERVICE IS

Hyundai Key Replacement in Worthing

Every modern Hyundai key has a chip hidden in its head, so a replacement Hyundai key is two jobs. The HY22 blade is cut to the locks, and the chip is coded so the immobiliser lets the engine run. Hyundai has changed its chip three times, and the chip in your car decides how the coding is done. It is the Hyundai side of car key replacement, and the other makes are listed under the car makes we cover.

Spare Hyundai Keys When One Key Still Works

With a working key, a new key is coded alongside it. It is the quickest and cheapest route on any Hyundai, and worth doing before the last key goes. The wider service is a spare car key.

CHIPS BY YEAR

Hyundai Transponder Chips by Model and Year

Hyundai moved from the ID46 chip to the ID47 and then to Hitag AES. The model and year point to the chip, and the chip decides the equipment and the time.

ModelID46, Hitag 2ID47, Hitag 3Hitag AES, ID4A
i102008 to 20132014 to 20192020 onwards
i202008 to 20142014 to 20202020 onwards
i302007 to 2011, some to 20162017 onwardsNewest versions
ix35 and TucsonSome 2010 to 2015 keysSmart keys 2016 to 20212022 onwards
KonaNot used2017 to 20232024 onwards

Some ix35, Tucson and i30 keys of the same years use a different 80 bit chip, known as DST80, which is why the registration is checked first.

KEY TYPES

Hyundai Key Types

Hyundai uses three main kinds of key.

The Hyundai Flip Key

The folding remote key with an HY22 blade, used on most i10, i20, i30, ix35 and Tucson models for many years. The blade, chip and remote sit in one head.

The Hyundai Smart Key

A proximity key for keyless entry and push button start, on higher trims of the i30, Tucson, Kona, Santa Fe and Ioniq. It is coded to the keyless system as well, the work covered under smart key replacement.

The Emergency Key

Every smart key hides an HY22 emergency key for the driver door. Hyundai key cutting for the blade is done in the van, as described under car key cutting.

BY MODEL

Hyundai Key Replacement by Model

Five Hyundai models, and the key each one uses.

Hyundai i10 Key Replacement

The i10 uses a flip key on most versions. Cars from 2020 carry the Hitag AES chip, while earlier ones use ID46 or ID47, all coded at the car.

Hyundai i20 Key Replacement

The i20 follows the same chip pattern as the i10, with a flip key on most cars and a smart key on some newer trims.

Hyundai i30 Key Replacement

Earlier i30 cars use an HY22 flip key with an ID46 chip. From 2017 the i30 moves to the ID47 chip, with a smart key on higher trims.

Hyundai Tucson Key Replacement

The ix35 and the Tucson that replaced it use flip keys or smart keys depending on the trim. The Tucson from 2022 uses Hitag AES, confirmed on the call for all keys lost.

Hyundai Kona Key Replacement

The Kona, including the electric version, uses a smart key or flip key with the ID47 chip to 2023, and Hitag AES on the newest cars.

WHAT IT COSTS

Hyundai Key Replacement Cost

Hyundai keys are among the more affordable to replace, but the chip and the smart key still move the price. These are typical 2026 UK prices.

JobMobile locksmithHyundai dealer
Standard replacement keyFrom £85Higher, key ordered first
Hyundai key, most models£95 to £150 plus VATHigher
All keys lostFrom about £130Varies by model
Hyundai smart key replacementHigher, agreed on the callUp to about £350

Most Hyundai keys are finished in one visit, in under an hour at the car.

COST FACTORS

What Drives the Cost of a Hyundai Key

Four things move the price of a Hyundai key.

The Chip Generation

ID46 keys cost least, ID47 keys a little more, and Hitag AES keys most.

Smart Key or Flip Key

A smart key for push button start costs more than a flip key.

Whether a Key Still Works

A spare costs less than all keys lost, where the lock is decoded first.

The Time of the Call

A night or weekend visit can cost more, and that is said on the call.

ALL KEYS LOST

Lost Hyundai Keys and All Keys Lost

With no key left, the HY22 blade is cut to code, and Hyundai key programming codes a new key through the OBD port. The lost keys are removed so they can no longer start the car, the step described under a car immobiliser reset. The full lost key process is under lost car keys.

The PIN Code

Hyundai key coding needs a security PIN tied to the VIN, obtained once the V5C and photo ID have been checked.

CHECK FIRST

Hyundai Key or Ignition Problems, Check These First

Not every Hyundai key fault needs a new key. These are the usual causes and what fixes each one.

What you noticeLikely causeWhat fixes it

Immobiliser light on, car will not startKey not recognisedCoding the key again

Blade bent or snappedOlder soft blades wear and breakA new blade cut to code
HYUNDAI AND KIA

Hyundai and Kia Keys

Hyundai and Kia are part of the same group and share blades and immobiliser systems, so a Tucson and a Sportage, or an i30 and a Ceed, are handled with the same equipment. The Kia side is covered under Kia key replacement. The Santa Fe, Ioniq, Bayon and older Getz follow the same flip key and smart key rules as the models above.

FAQS

Questions About Hyundai Key Replacement in Worthing

The questions asked most about Hyundai keys, from chips and cost to lost keys.

A Hyundai key usually starts from £85 to £150 plus VAT with a mobile locksmith, with smart keys and all keys lost costing more. A dealer can charge up to £350 for a smart key. The price for your car is agreed on the call.

It follows the model and year. Most Hyundais to about 2013 use the ID46 chip, later cars the ID47 Hitag 3 chip, and the newest the Hitag AES chip. The registration confirms it.

Usually the battery or the remote circuit. A new battery comes first, then a remote car key repair if the buttons still fail.

Usually not. A worn flip or split case is a car key fob repair, which keeps the chip and costs less than a Hyundai key fob replacement.

The broken piece is removed first, then a new blade is cut to code. The removal is covered under broken car key extraction.

Under an hour at the car for most Hyundais, and longer when every key is lost.

Yes, on most Hyundais. The HY22 blade is cut to code and the new key coded at the car. The newest Hitag AES models are confirmed on the call.

Yes. The chip is hidden in the head of the key and coded to the immobiliser, as described under transponder key programming.

It helps. On many Hyundai models the key list is relearned, so bring every key you still have to keep them all working.

Yes. Hyundai keys are replaced at the car across Worthing, Goring, Lancing, Shoreham-by-Sea and the rest of the 15 towns covered.
