I know this is an older post but I purchased this exact Alarm module 5326 last 4#’s and it works for the unlock as it beeps once. It does not however beep 3 times like it should when locking. Does anyone by a glimmer of a chance know how to activate that function? I know it’s a long shot as ours originally didn’t have this feature. I’m wondering if it has anything to do with deactivating the TPMS through the dome light method, as they’re both on the same fuse. Thanks any and all in advance for help.
