Are you looking to program a key fob or a new ignition key for your 1999 Ford Expedition? Understanding the process can save you time and money. This guide provides clear instructions and options based on your current situation.
Programming a 1999 Ford Expedition Ignition Transponder Chip Key
The 1999 Ford Expedition uses a transponder chip key for security. Programming these keys requires specific procedures and, in many cases, specialized equipment. Here’s a breakdown of your options depending on how many working keys you currently have:
Scenario 1: No Existing Working Keys
If you’ve lost all your keys, unfortunately, you cannot program a new key yourself. Here are your options:
-
Automotive Locksmith (Preferred): Calling a mobile automotive locksmith is often the most convenient and cost-effective solution. A qualified locksmith can come to your location and originate a new key for your 1999 Ford Expedition. They possess the necessary tools and computers to bypass the security system and program a new transponder key specifically for your vehicle.
-
Dealership: Alternatively, you can have your vehicle towed to a Ford dealership. Dealerships have the equipment to originate and program new keys. However, this option can be more expensive and less convenient than using a locksmith due to towing costs and dealership service scheduling.
Scenario 2: One Existing Working Key
Even with one working key, you still cannot program a second key yourself for your 1999 Ford Expedition. The process requires specialized diagnostic equipment. Your options are:
-
Automotive Locksmith (Preferred): An automotive locksmith is again a great choice. They can program a second key for you, coming to your location or at their shop, using specialized computer equipment connected to your vehicle’s onboard system.
-
Dealership: Visiting a Ford dealership is another option. They can program a second key, but it may be a more time-consuming and potentially more expensive option compared to a locksmith.
Scenario 3: Two Existing Working Keys
If you already have two functioning keys, you can program a third key yourself after having the new key cut by a locksmith. Here’s how:
-
Insert First Working Key: Place an existing, working key into the ignition cylinder.
-
Turn Ignition ON and OFF: Turn the ignition key to the ON (RUN) position, then immediately turn it back to the OFF position.
-
Insert Second Working Key: Remove the first working key. Within five seconds, insert your second working key into the ignition cylinder. Turn this key to the ON (RUN) position and then back to OFF.
-
Insert New Key: Remove the second working key. Before ten seconds elapse, insert the new, uncut key into the ignition cylinder. Turn the new key to the ON (RUN) position and leave it in the ON position for one second. Then, turn it back to the OFF position.
-
Security Light Confirmation: Watch the security light on your dashboard. If the programming is successful, the security light will illuminate for three seconds. This indicates that your new key has been successfully programmed to your 1999 Ford Expedition.
