2009 Jeep Grand Cherokee Key Fob Programming Help
Getting stuck with a remote that will won't cooperate is definitely a massive pain, but 2009 jeep grand cherokee key fob programming is something almost all owners have to deal with eventually. Whether your control keys just threw in the towel the particular ghost or you've finally made a decision to get a spare so you aren't stranded if you lose your main, there's a specific way the 2009 models handle these types of things. It isn't always as simple because the older Jeeps making it possible to just circuit the locks, yet it's also not a total mystery once you understand the guidelines.
The particular "Two Working Keys" Rule
When you're looking regarding a way to try this yourself within your driveway with no spending a penny on professional help, there's one big catch: you need two working secrets. This is portion of Chrysler's "Sentry Key" security system. Basically, the car wants proof that you're the proprietor and not really someone trying to hack into it, so it requires two special, already-programmed keys in order to authorize a third one.
When you happen in order to have two tips that both start the engine, you're in luck. A person can buy a blank fob online intended for twenty bucks plus program it in about sixty seconds. You just place the first legitimate key within the ignition, turn it in order to "On" (don't start the engine), wait about five in order to ten seconds until the security light starts flashing, and then swap it regarding the second key. Once that second key does the thing, the vehicle gets into "Programming Mode. " At that point, you stick the particular new, unprogrammed key in, and the Jeep "learns" it.
It sounds basic because it is—provided you haven't already lost your extra. If you just have one operating key right this moment, I actually hate as the bearer of bad news, but you won't be able to do the DIY method. The car won't let you. It's a security function to stop valets or random people from making duplicates of your key without you understanding.
What if You Only Have One Key?
This is where most people find themselves. You bought the particular Jeep used plus it only included one key, or your second key broke years back. For 2009 jeep grand cherokee key fob programming when you only have one key, your choices get a bit more expensive.
You'll essentially need someone with a specialized check tool that can plug into the particular OBDII port (the little plug below your dashboard) and bypass the safety lockout. You have three main paths here: the store, a mobile locksmith, or purchasing a DIY programmer kit.
The dealership will be the most obvious choice, but honestly, it's usually the most expensive. They'll likely charge a person an hour or so of labor just to hook upward their computer, which usually can run any where from $100 to $200 depending on where you live. Plus, they often refuse to program tips you bought upon eBay or Amazon online, insisting that a person buy their "official" Mopar parts in a massive markup.
Why Locksmiths Are Usually the Better Bet
If I were in this position, I'd call a local automotive locksmith prior to heading to the particular dealer. Most associated with these guys are usually mobile, so they'll come to your house or office, which is far more convenient. They carry the same types of computers the dealerships use, and they're usually much more relaxed about programming aftermarket keys.
The cool thing about locksmiths is that they will do this all day every day. They understand the quirks associated with the 2009 Grand Cherokee (the WK generation). They understand that sometimes the particular WIN (Wireless Combustion Node) module could be finicky. They'll frequently give you the flat rate intended for the service as well as the key combined, which often ends up becoming significantly cheaper than the dealership's "service fee + components + tax" headache.
Those DO-IT-YOURSELF Programming Tools A person See Online
You've probably observed those "Simple Key" kits at big-box hardware stores or on Amazon. Offered with a brand-new key and also a small plastic dongle that you plug into your Jeep. These can become a lifesaver when you only have 1 key and don't want to pay out a locksmith.
They work by mimicking the dealership's computer. A person plug the kopierschutzstecker into the interface under your dash, stick to a number of steps (usually involves turning the key and pushing buttons), and this forces the car to accept the new fob. They're generally reliable, but make sure the one you buy specifically mentions the 2009 model year. Chrysler changed the key style and the particular computer protocols the few times in that era, so the kit for the 2004 Jeep won't focus on your 2009.
Is it a Battery Concern or a Programming Issue?
Before you spend a cent on the new key or even a programming service, do yourself a favor and verify the battery. This might sound obvious, but you'd be surprised the number of people think their particular programming "fell out" of the car's memory when the particular battery just died.
The 2009 Grand Cherokee uses a FOBIK-style key—that's the rectangular plastic material piece that a person actually stick directly into a slot on the dash. Within that fob is really a CR2032 coin battery. If your Jeep starts fine yet the remote lock/unlock buttons don't function, it's most likely the battery or the inner contacts.
Pop the crisis metal key out of the bottom of the fob, and use it to gently pry your invisalign aligner case apart. If the battery is outdated, replace it. When the buttons still don't work, look at the little silicone pad inside. More than time, the conductive material on the back of the buttons wears away from. You can actually buy "button repair kits" or just swap the internals into a cheap new shell to repair this without requiring any new programming.
Buying the particular Right Replacement Fob
Should you choose need a new a single, don't just purchase the first thing you see. For the 2009 model year, you should match the FCC ID on the back of your own current key. Generally, it's something similar to M3N5WY783X .
There are also various versions depending upon your Jeep's features. If your Jeep has a strength liftgate or remote control start, your fob needs the additional buttons for all those functions to work. You can technically program a 3-button fob to a Jeep that included a 5-button fob, but you'll certainly lose those extra functions. However, you can't usually move the other way—if your Jeep doesn't possess the hardware with regard to remote start, buying a fob along with a remote start button isn't likely to magically make your engine start from your living space.
The Maintenance Phase
Sometimes you follow the guidelines perfectly and the car just will not work. If you're trying the two-key DO-IT-YOURSELF method and it's not working, check the dashboard. Will be the red safety light blinking quickly? That usually means the vehicle doesn't identify among the keys because "valid, " or the new key you're seeking to add is a dud.
Also, keep in mind that most Jeeps have a limit on how many keys can be programmed with once—usually eight. When you're the 5th owner of this Jeep and everybody else produced a bunch associated with spare keys, the particular memory might end up being full. If so, a person definitely need the locksmith or the dealer to "wipe" the existing key list and begin fresh.
Having to wrap it Up
Working with 2009 jeep grand cherokee key fob programming is one of these things that seems like an enormous chore until you get it done. If you've got two keys, take five minutes this particular weekend and plan another one just in case. It'll cost you twenty bucks for the blank key and save you 100s later.
If you're right down to your last key, don't wait unless you lose it. Becoming "all keys lost" is a much more expensive issue to solve because a locksmith will certainly have to choose your lock and generate a brand-new key from the beginning. Spend the bit of cash now to obtain a spare, whether you go the particular locksmith route or even use a DO-IT-YOURSELF plug-in tool. It's one of those bits of preventative maintenance that actually gives you some peace associated with mind. Plus, it's just nice to have a remote that actually works when your own hands are full of groceries.
