Here are the key points:<\/p>\n<ol start=\"1\" data-spread=\"true\">\n<li>4A Smart Key Cannot Be Unlocked by Most Tools\n<ul data-spread=\"false\">\n<li>The ID4A chip in Toyota vehicles such as the Corolla, Corolla Cross, and new Camry uses Hitag 3 with AES encryption.<\/li>\n<li>This chip differs from the older 8A chip family and is not compatible with standard unlocking tools.<\/li>\n<li>Tools like Xhorse VVDI Mini Key Tool, Autel IM series, and Lonsdor K518 Pro cannot unlock ID4A keys.<\/li>\n<\/ul>\n<\/li>\n<li>Only MK Tool Supports Unlocking 4A Keys\n<ul data-spread=\"false\">\n<li>Currently, the only known tool capable of unlocking the 4A smart key is the MK Tool.<\/li>\n<\/ul>\n<\/li>\n<li>However, Unlocking May Not Be Necessary\n<ul data-spread=\"false\">\n<li>When adding a key (Add Key), 4A keys typically do not lock and can be programmed directly to another vehicle.<\/li>\n<\/ul>\n<\/li>\n<li>All Keys Lost Situation\n<ul data-spread=\"false\">\n<li>In the case of all keys lost (AKL), you need to:\n<ul data-spread=\"false\">\n<li>Use a key emulator (such as KD, Lonsdor, or TANGO) to simulate a key.<\/li>\n<li>Backup the vehicle&#8217;s immobilizer data.<\/li>\n<li>Program the emulator first, then transfer the data to a used key.<\/li>\n<li>Using an emulator bypasses the need for unlock codes.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p><strong>Conclusion<\/strong>: You cannot unlock a 4A smart key with <a href=\"https:\/\/www.obd2tool.com\/category-188-b0-Xhorse.html\">Xhorse<\/a>, <a href=\"https:\/\/www.obd2tool.com\/category-37-b0-Autel+Tools.html\">Autel<\/a>, or <a href=\"https:\/\/www.obd2tool.com\/category-211-b0-Lonsdor+Programmer.html\">Lonsdor<\/a> at present. Only the MK Tool has limited support. Fortunately, unlocking is often unnecessary when adding a key. For all keys lost, emulators and proper data backup are essential.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>Question: Is it possible to unlock the 4A smart key from a 2023 Toyota Corolla Cross using tools like Xhorse,<!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":1,"featured_media":23116,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[11,2040],"tags":[3839,3840,1507],"views":1373,"_links":{"self":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts\/23115"}],"collection":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/comments?post=23115"}],"version-history":[{"count":1,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts\/23115\/revisions"}],"predecessor-version":[{"id":23117,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/posts\/23115\/revisions\/23117"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/media\/23116"}],"wp:attachment":[{"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/media?parent=23115"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/categories?post=23115"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.obd2tool.com\/blog\/wp-json\/wp\/v2\/tags?post=23115"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
