Review: Excelente producto Me encanto la llave funciona de maravilla La recomiendo ampliamente Mi coche es un cadíllac CTS 2008 Un punto a destacar es que te dicen como programarla y asi evitas altos costos Review: When in hand I can open the doors and trunk. I can also lock and unlock the doors. Unfortunately using the key fob I cannot remotely open the trunk nor start the car with the key fob. Sadly the blank key in the key fob is the wrong size and cannot be cut to be able to open the driver side door. I hope Keyecu will be able to remedy these shortcomings. Will let you know. Update: Keyecu sent me a replacement keyfob. Blank key is the right size and all remotes are working. Now five stars ... many thanks. ## Features - Replace FCC ID: M3N5WY7777A;OE #:25943676, 25943677 - 5 Button :Lock, Unlock, Panic, Trunk, Remote-Start, - Please confirm your key insert blade style is an exact match prior to purchase. - Fit for CTS 2008-2013 /STS 2008-2013 - The remote and transponder chip needs to be programmed and the key blank needs to be cut at your local dealer or qualified automative locksmi before you can use it. ## Technical Specifications | Specification | Value | |---------------|-------| | Number of Buttons | 5 | | Model Name | Smart Key - M3N5WY7777A / 25943676 | | Manufacturer | Keyecu | | Package Dimensions | 11.05 x 7.49 x 1.4 cm; 41 g | | Batteries | 1 CR2 batteries required.

Some of the ones I have purchased either will not program or they do not tell you that it needs to be programmed by a dealer. This one was programmed already and all the functions work properly .I have been very pleased with my purchase and would recommend it. ## Frequently Bought Together - Keyecu Replacement Smart Remote Key Fob 5 Button for Cadillac STS CTS 2008-2013 - Smart Key Fob Case Shell Fit for Cadillac STS CTS 2008 2009 2010 2011 2012 2013 Replacement Keyless Entry Remote Car Key Housing Casing Outer Cover with Uncut Blade Blank (1) - MILD EAST for Cadillac Key Fob Cover with Keychain, 5-Button Key Case for Escalade SRX CTS ATS XTS DTS STS 2008-2014 2015, Soft TPU, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/340029690-keyecu-replacement-smart-remote-key-fob-5-button-for-cadillac](https://www.desertcart.co.uk/products/340029690-keyecu-replacement-smart-remote-key-fob-5-button-for-cadillac) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-27*
