My Honest Experience With Top ezs mercedes programmer Tools on AliExpress

When my old Mercedes E-Class started showing those mysterious “EZS communication” errors, I knew it was time to dive into the world of car electronics. I’m 38, an auto electrician by trade and a bit of a geek for diagnostic gear. Over the years, I’ve helped dozens of customers (and friends) resurrect “dead” Benz keys, reset immobilizers, and even bring back ECUs thought to be beyond saving. That’s why I decided to test several top-selling ezs mercedes programmer tools from AliExpress — to see which ones truly work and which are just hype. This review is based entirely on my own purchases, hands-on experience, and a fair bit of trial and error.

R270+ V1.20 Car Key Prog SRS Programmer For Mercedes Benz EZS

I started my ezs mercedes programmer review journey with this classic R270+ V1.20 — one of the oldest but most trusted devices for Benz and BMW modules. It came in a sturdy plastic case with adapters for M35080, CAS, and EZS chips. Delivery took 17 days to Ukraine, which is decent.

Setting it up was straightforward, though the driver installation required a little manual tweaking (classic). Once running, the programmer read an EIS dump from my W211 flawlessly. Writing to the M35080 EEPROM also went smoothly. The interface isn’t modern, but it does the job.

Pros: affordable (~$38), wide compatibility, includes all cables. Cons: outdated software UI, no automatic updates.

Compared to local suppliers, it’s half the price. For anyone starting in EZS repair — this one’s a solid base tool.

R270+ V1.20 Car CAS4 BDM Auto Key Programmer For Benz EZS

This version adds CAS4 BDM functions, and I bought it mainly to handle newer modules. I used it on a W204 EZS, and the read speed was noticeably faster than the older R270+. It even supported BDM connection without extra adapters.

What impressed me most was its stable connection — no random freezes mid-operation. I’ve seen that with cheaper clones. The ezs mercedes programmer buy choice here was a good call for the price.

Pros: stable BDM reading, faster operation. Cons: instructions are vague; had to find tutorials on YouTube.

Worth every cent for technicians who handle post-2010 Benz models.

AK90+ V3.19 Key Maker For BMW CAS/EZS

Now, technically it’s a BMW tool, but since it supports EWS/EZS reading, I decided to give it a spin. The ezs mercedes programmer reviews section on AliExpress was full of praise, and rightfully so. It’s small, lightweight, and doesn’t need external power.

For BMWs, it’s a monster — quick, reliable, accurate. For Benz EZS, not as universal as R270+, but great for quick key data extraction.

Pros: compact, plug-and-play, solid performance. Cons: limited to older systems.

It’s more of a complementary tool than a replacement for a dedicated EZS programmer.

Xhorse XDKP30 Multi-function Adapter (for MINI Prog, Key Tool Plus)

This Xhorse adapter was a bit of a splurge. I got it for about $62, hoping to use it for both Benz EZS and ECU renewals. It connects neatly to the Xhorse ecosystem — I already had the Key Tool Plus tablet, so integration was seamless.

I tested it on an ELV and EIS board. Worked like a charm! The solderless connection feature really speeds up workflow. This product shows how far programming gear has evolved.

Pros: fast, multi-brand support, no soldering needed. Cons: requires Xhorse base device.

If you’re serious about diagnostics, this is one of the top ezs mercedes programmer tools to buy.

VXDIAG VCX DoIP VD410 Mercedes Benz C6 OBD2 Diagnostic Scanner

Here’s where things get more serious. The VD410 is a full-fledged dealer-level scanner. I use it for ECU coding, reading fault codes, and programming. Setup took a bit, but once connected to Xentry — it’s pure magic.

I coded a new EZS on a W212 — success! The tool communicates perfectly with DAS and Xentry software. Delivery took 20 days, but it came well-packed.

Pros: genuine J2534 support, professional-grade functions. Cons: needs a powerful laptop, software setup takes time.

In short, it’s not a toy — it’s a proper ezs mercedes programmer device for pros.

CGDI Prog MB for Benz Car Key Programmer with ELV/NEC Adapter

This was the star of my lineup. The CGDI Prog MB simply delivers. I used it for key addition, reading password from EIS, and even an all-key-lost situation. It finished tasks that would take hours on cheaper clones — in minutes.

The software updates regularly and supports almost every modern Benz key system. It’s pricier (~$245), but for workshops, it’s a must-have.

Pros: fastest EZS password read, frequent updates, stable. Cons: expensive for hobbyists.

This one raised the bar in my ezs mercedes programmer reviews project.

Autel MaxiIM IM508S IMMO & Key Programmer

Autel never disappoints. I grabbed this during a sale, and honestly — it’s the Swiss Army knife of key tools. It works on Benz, BMW, VW, you name it. With EZS/EIS programming, it’s incredibly intuitive.

Autel’s support and updates make a difference. I managed to sync a new EZS and program two keys on my W211 in under 30 minutes. The tablet interface is smooth, and customer service is responsive.

Pros: user-friendly, multi-brand, pro-grade quality. Cons: pricey (~$799), requires updates.

Still, if you want an all-in-one tool — this is your ultimate ezs mercedes programmer buy.

It’s a must-have companion for anyone who works with EZS modules daily.

VXDIAG VCX VX800 Benz MB Star C6 Scanner

My final purchase in this Top ezs mercedes programmer collection was the VX800. Essentially an upgraded VCX SE — faster communication, better DoIP support, and slicker housing.

Pros: fast DoIP connection, modern interface. Cons: a bit expensive, but worth it for professionals.

If you want future-proof diagnostics, this one’s the way to go.
