¿Qué es el mando inteligente Valeo IM3A para Peugeot?

What the Valeo IM3A Is and Which Cars Use It

The Valeo IM3A is an original-equipment smart key fob (also called a proximity key or keyless entry remote) manufactured by Valeo, one of Peugeot's primary electronics suppliers. Unlike a traditional remote, a smart key allows passive entry and push-button engine start without physically inserting a key — the car detects the fob when it is within a set range.

This specific unit fits the following Peugeot models built from the 2021 model year onwards:

| Model | Generation / Year | |---|---| | Peugeot 208 | 2021+ | | Peugeot 2008 | 2021+ | | Peugeot 308 | 2021+ | | Peugeot 408 | 2021+ | | Peugeot 3008 | 2021+ | | Peugeot 5008 | 2021+ | | Peugeot 508 | 2021+ |

If your vehicle is an earlier generation — for example, a pre-facelift 308 or the first-generation 2008 — this fob will not be compatible. Always confirm your build date, not just the model year badge.

How to Identify the IM3A by OEM Number and Label Markings

The OEM reference printed on the fob's internal PCB or on a sticker inside the battery compartment is IM3A. When you open your current key fob (usually by pressing a small release tab and sliding out the emergency blade), look for:

• The alphanumeric code IM3A stamped or printed on the circuit board or housing label
• The Valeo brand name or logo
• A frequency marking (typically 433 MHz for European-market Peugeots)

If your fob's label is worn, cross-check using your car's VIN through the Peugeot parts catalogue or your dealer's system to confirm the correct key reference for your build date and trim level.

Cross-Reference Numbers

No third-party or OEM cross-reference numbers are confirmed for the IM3A at this time. Because smart key fobs contain paired transponders and encryption, substituting an unverified alternative can result in a unit that cannot be programmed to your vehicle. Stick to the IM3A reference to avoid compatibility issues.

What to Check Before Buying

1. Build date, not model year — Peugeot updated several platforms mid-cycle. Verify your vehicle's production date on the VIN plate (door pillar or bonnet) to confirm it falls in the 2021+ range.
2. Keyless entry system fitted — Not all trim levels include the keyless (hands-free) entry system. Check your vehicle spec sheet or owner's manual; if your car uses a conventional remote, the IM3A smart key will not function.
3. Programming requirement — A new smart key fob must be programmed (paired) to your vehicle using a compatible diagnostic tool, typically at a Peugeot dealer or a workshop with PSA-compatible software. Factor this into your total cost.
4. Condition — This part is sold as new, which means no pre-owned wear or unknown programming history.
5. Battery — Confirm whether a CR2032 or equivalent cell is included, or plan to purchase one separately.

FAQ

Can I program the IM3A myself at home?

Smart key fobs for 2021+ Peugeot models generally require dealer-level or professional diagnostic equipment to pair. Unlike older button-only remotes, there is no published DIY sync sequence for keyless smart keys on these platforms. Plan to have it programmed by a dealer or a workshop with PSA-compatible diagnostics.

Will one IM3A fob work on different Peugeot models from the list?

Physically the fob is the same unit across these models, but it must be electronically paired to a specific vehicle. A fob programmed to your 308 cannot simply be used on a different car — it would need to be erased and re-programmed.

Is this the same key fob as the pre-2021 Peugeot smart keys?

No. Peugeot revised its keyless entry system with the 2021+ generation. Earlier fobs use different OEM references and are not interchangeable with the IM3A.
