OBDSTAR has pushed a major software update that brings 2024-and-newer Citroën, Peugeot, DS, and Toyota models into its key-programming workflow. The release adds ID4A PIN code reading through the KeySim function, proximity (smart) key programming, and ID box with steering lock programming across three X300-series tools.

What the OBDSTAR Update Covers
The update lands in two versioned branches. Citroën/Peugeot/DS coverage moves to V42.88, while Toyota coverage moves to V43.29.
On the PSA side, V42.88 adds 2024- ID4A PIN code reading through the KeySim function — the step that lets a locksmith extract the immobilizer PIN needed to add a new key — plus proximity key programming for a long list of models. Peugeot coverage spans the 208, 308, 3008, 408, 408X, 5008, and 508 families, along with vans like the Rifter, Partner, Expert, and Traveller. Citroën gets the C3 through C6 ranges, Berlingo, Dispatch, Jumpy, and SpaceTourer; DS picks up the DS 3 through DS 9. Electric variants — the E-208, E-2008, E-3008, E-C3, E-C4, and their commercial siblings — are included too. PSA-based Toyota vans (ProAce, ProAce City, and their electric versions) are also covered.
For shops that have worked on late-model Peugeot and Citroën vehicles, the ID4A immobilizer is a known bottleneck. It uses a rolling PIN scheme that older tools could not extract on-vehicle, forcing technicians to either pull the BSI module for a bench read or call a dealer for a code. KeySim removes that step by reading the PIN directly through the OBD connection — the difference between a fifteen-minute add-a-key job and one that stalls halfway through.
The Toyota branch, V43.29, adds proximity key programming, immo data reading, and ID box programming with steering lock for the 2024-2026 Corolla, Highlander, and Crown Kluger. Regions span Asia, Europe, USA-Canada, South America, Africa, and Australia — coverage that is genuinely global rather than locked to a single market.

Why It Matters for Locksmiths and Key Programmers
Newer PSA and Toyota platforms have made all-keys-lost and spare-key jobs harder, not easier. ID4A-class immobilizers and later Toyota proximity systems routinely lock the PIN behind dealer portals, which pushes independent locksmiths toward expensive dealer visits or turning the job away. An update that reads the PIN in-shop and programs the proximity key directly changes the economics of those jobs.
For a busy shop, the payoff is concrete. A proximity key add that once meant an hour of manual immo data handling — or an outsourced PIN read — can now be completed with a dedicated key programmer in a single bench session. The Toyota steering-lock and ID box programming is the same story: tasks that previously required separate procedures or hardware are now folded into one tool's workflow.
There is also a real cost angle. Shops that already own an OBDSTAR X300-series tool get this expansion through a software update rather than a new hardware purchase. That matters when dealer-level key coverage keeps creeping up in price.
The commercial and fleet angle matters too. Models like the Expert, Dispatch, Jumpy, Traveller, Berlingo, and Partner are workhorses for couriers and trade fleets across Europe, and they are now aging into the used market where key jobs are routine. Being able to program a proximity key for a 2024-2025 van without a dealer portal turns a common fleet request into walk-in work for an independent shop.

Which OBDSTAR Tools Get the New Functions
The new coverage is available on three X300-series programmers:
- OBDSTAR X300 Classic G3 — the entry workhorse for general key programming
- OBDSTAR X300 Pro4 — the higher-spec unit for proximity and immo-heavy workflows
- OBDSTAR X300 Mini PSA — the PSA-focused compact option
All three require the latest software build to unlock the new menus. As with any immo work, correct transponder and key chips and the right remote or smart key remain prerequisites — the software covers the coding, not the physical hardware.

What to Expect Next
OBDSTAR's release cadence has been steady through 2026, with each cycle filling in the newest platform generation for a specific brand group. The pattern here — PSA first, then Toyota's proximity systems — suggests the roadmap is trending toward 2025-and-newer smart-key platforms across the major volume brands. For shops deciding where to put their key-programming budget, ongoing update behavior and per-tool coverage differences are worth watching before committing.
Keep your software current and verify coverage against your local model mix before quoting a job. The safest move is to update, then run a known-good spare-key test on a supported vehicle before taking on a paid all-keys-lost job. Always back up the original immo data before programming, and keep the tool's firmware and the vehicle battery voltage stable during any write operation to avoid bricking a module.
