Great for the older toyotas ### ⭐⭐⭐⭐ 4.0 out of 5 stars Want to avoid the high price of keys from dealerships? *by C***O on Reviewed in the United States on December 30, 2023* Purchased this item after being quoted $250 for "smart" key replacement by my local Toyota dealer. So now with the price of the key blank (make sure you get the right one, not the cheapest one!) I can clone my current key for a fraction of the price. A great deal if you have multiple cars in your driveway you can use it on, so really good if you are a Toyota family whose cars fall within the specified age range for the device. Good gift for the amateur Toyota mechanic in your life. --- ## 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/553585576-obd-ii-smart-key-obd-key-programming-for-toyota-can](https://www.desertcart.co.uk/products/553585576-obd-ii-smart-key-obd-key-programming-for-toyota-can) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-09-08*
