Spare keysRegain Entry Into Your Citroën C3 Aircross
Lost your Citroën C3 Aircross key or keyless fob? On a compact SUV that does the family runs, the dog walks and the weekend away, being locked out or immobilised is more than an inconvenience — it stops the household in its tracks.
A dealer will typically want the Aircross recovered, a booking days out, and a bill covering the smart fob, the coding and the transport. A general locksmith usually cannot touch it: the C3 Aircross is a newer PSA / Stellantis SUV that needs current software and the correct HU83 smart-key blanks, which many do not carry. Older tooling will not authenticate to the car.
Lock City keeps its PSA / Stellantis software and stock current specifically for cars like the Aircross. We come to you, supply the right smart key or flip key, and code it to your immobiliser at the roadside — no towing, no dealer wait, fully guaranteed.

Citroën C3 Aircross Keys: Types & What You Need
The C3 Aircross launched in 2017 as a compact SUV sitting above the C3 hatch, so its key system is entirely modern PSA / Stellantis — which is exactly why up-to-date software matters here:
C3 Aircross (2017–present)
- Blade: HU83 high-security profile (emergency blade for the door if the fob battery dies).
- Key: flip (switchblade) remote on entry trims; keyless entry & go (proximity smart fob) common on higher Flair / Shine trims.
- Transponder: Hitag2 (ID46) on early cars, with more secure AES chips on later builds.
- Facelift (2021-on): refreshed under Stellantis; same HU83 key architecture, keyless still trim-dependent.
- All-keys-lost: roadside-programmable with current software; keyless AKL takes longer than adding a spare.
What we see most on the C3 Aircross
- One-key households: many were sold with a single smart fob, so a lost key is instantly an all-keys-lost.
- Flat fob batteries mistaken for a failed key — often just a CR2032 swap plus the emergency-blade entry.
Note: as a newer model spanning the PSA-to-Stellantis change, exact keyless availability and chip revisions vary by trim and build date [verify against your VIN]. Tell us your reg and we will confirm the software and blank needed before we set off.
Citroën C3 Aircross Key Replacement — Your Questions Answered
Can you programme a keyless Citroën C3 Aircross key?
Yes. Higher-trim C3 Aircrosses use a keyless entry & go smart fob, and we carry both the HU83 blanks and the current PSA / Stellantis software to programme one to your SUV at the roadside — including all-keys-lost.
My Aircross came with only one key — should I get a spare?
Strongly recommended. Many C3 Aircrosses were delivered with a single smart fob, so losing it turns a simple spare-cut into a costlier all-keys-lost job. A programmed spare now is cheaper and saves you being stranded later. See our car key replacement service.
My C3 Aircross won’t detect the key — is the fob dead?
Often it is just a flat CR2032 battery in the smart fob. You can usually still start the car by holding the fob to the marked spot and get in with the hidden emergency blade. If a new battery does not fix it, we can test and, if needed, replace the fob.
How much does a keyless C3 Aircross smart key cost?
A keyless Aircross smart fob sits in the higher price tier because the part is more expensive and the programming takes longer than a basic flip key. Send us your registration and we will confirm the exact cost before we travel.
Is the keyless C3 Aircross at risk of relay theft?
Like any keyless car, yes — so keep the fob in a Faraday pouch and the spare away from the front of the house. If a keyless fob is lost or stolen, we can programme a new one and disable the old. See our stolen car keys service.
