So kaufen Sie den Valeo IM3A Smart Key Fob für Citroën
Der Valeo IM3A ist ein neuer original Smart Key Fob für Citroën C3, C4, C5 Aircross und Berlingo Modelle ab 2021. Dieser Leitfaden erklärt, wie Sie ihn anhand der OEM-Nummer identifizieren, was Sie vor der Bestellung prüfen sollten und was Sie erwarten können.
What Is the Valeo IM3A and Which Cars Use It?
The Valeo IM3A is a new, genuine smart key fob designed as original equipment for a range of modern Citroën models. Unlike basic remote keys, a smart key allows keyless entry and push-button ignition — the car detects the fob in your pocket without you pressing anything. Valeo is one of Citroën's primary OEM suppliers for keyless access systems, so this is not an aftermarket copy but a factory-grade part.
Compatible models (2021 and later):
- Citroën C3
- Citroën C4 / e-C4 (electric)
- Citroën C4 X
- Citroën C5 Aircross
- Citroën C5 X
- Citroën Berlingo (Mk3 facelift)
If your car left the factory after 2021 and originally came with a hands-free access system, there is a good chance this fob is the right match. Always verify before purchasing (see checklist below).
How to Identify the IM3A by OEM Number and Label Markings
The OEM reference you need is IM3A — this is the Valeo part number printed on the fob's internal PCB label and often on the packaging. When you receive the key, you can confirm it by:
- Removing the emergency metal blade (usually released by a small button on the side).
- Carefully opening the fob shell (a thin plastic pry tool helps).
- Reading the PCB label — it should show IM3A and the Valeo logo.
On the exterior, genuine Valeo fobs have clean, evenly moulded Citroën chevron branding, a solid tactile button feel, and no rough parting lines on the plastic shell. If the markings look faint or asymmetric, question the source.

Cross-Reference Numbers
No third-party cross-references have been confirmed for the IM3A at the time of writing. Using the Valeo OEM reference IM3A is currently the most reliable way to search. If you find alternative part numbers listed elsewhere, compare them against the original Citroën workshop documentation before ordering.

What to Check Before Buying
Smart key fobs are vehicle-specific and require professional programming before use. Before placing your order:
- Confirm your model year — the IM3A fits 2021+ variants; earlier facelifts used different hardware.
- Check your existing fob — open it and read the PCB label. If it already shows IM3A, this is your replacement.
- Verify your car's access system — not all trim levels include hands-free access. Check your original owner's manual or the window sticker.
- Budget for programming — a new fob must be paired to your car's BSI unit by a Citroën dealer or a locksmith with compatible diagnostic equipment. The fob price does not cover this step.
- Battery type — genuine IM3A fobs use a standard CR2032 coin cell, widely available, but the new unit ships without a battery in some markets.

FAQ
Can I program the Valeo IM3A myself at home?
No. Smart key fobs for these Citroën models require BSI pairing using manufacturer-level or compatible diagnostic software. This is not a DIY task with a standard OBDII reader.
Will this fob work if my car already has a damaged key registered to it?
Yes, but the damaged key should be removed from the car's memory during programming. A qualified technician can delete old keys and register the new IM3A in the same session.
Is this the same fob used on the Peugeot 208 or 308?
Some Stellantis-platform vehicles share Valeo keyless hardware, but fob shells, button layouts, and BSI calibration differ between brands. Do not assume cross-brand compatibility without checking the specific part number against your vehicle's documentation.
