About This Product

Aftermarket remote key

Audi A8 S8 Aftermarket 3 Button Keyless Flip Remote Key 433MHz ID46 (PCF7943) HU-HAA/HU66

Check the part code, frequency, chip, blade/profile, button layout and keyless configuration against your existing key before ordering.

This aftermarket flip remote key is designed for Audi A8 S8. Key details include 3 Button, 433MHz, ID46 (PCF7943), HU-HAA/HU66. It is ideal as a spare or replacement remote key when the original is lost, damaged or unreliable.

Fitment checks

  • Match the part number, frequency, button layout, blade/profile and case shape against your existing key.
  • Known part/reference codes: 4E0837220 / REMOTEPCF7943.
  • Registration, make/model/year and catalogue data can be wrong on crossover-year vehicles or cars with added extras.

Programming required

  • Most remote keys need professional programming; this usually cannot be done remotely.
  • Online videos often show re-syncing an existing remote after a battery change, not programming a new key.
  • Keystation offers in-store programming in Essex and the vehicle may be required.

Tool & fault notes

  • A remote showing as locked on a tool does not always mean it is faulty or unusable.
  • Some machines cannot read every frequency, for example certain tools may not read 868MHz keys.
  • If programming fails, try a suitable alternative machine before assuming the remote is faulty.

Dispatch & returns

  • Parts are checked before dispatch for visible damage, remote operation, transponder status and key ID where applicable.
  • A fresh battery is fitted in most cases, usually a premium Renata battery, and checks are logged on the order.
  • Once cut, programmed, modified, soldered or locked to a vehicle, remote keys are usually non-returnable.
