2007-2014 Cadillac Chevrolet GMC Key Fob OUC6000066 for Keylessbest

If you lost your original Cadillac remote, cracked the case, or your buttons only work when they “feel like it,” this Cadillac OUC6000066 key fob is built to be a direct, locksmith-programmable replacement—without dealer pricing.

Who This Cadillac Key Fob Is For

• Cadillac 6 Buttons
• Frequency: 315MHz
• FCC ID: OUC6000066
• IC: 850K-6000066
• P/N: 22756466, 27607061

• 2007 – 2013 Chevrolet Suburban

• 2007 – 2013 GMC Yukon

If you still insert a metal key into the ignition (no push to start button) and your original remote shows FCC ID OUC6000066, this is the style you need.

If your FCC ID or system type is different, the car simply will not accept programming—no matter who tries. Matching FCC ID OUC6000066 is the only way to be sure this remote will work.

If your model matches the years and uses a non proximity system with FCC ID OUC6000066, this is the correct complete replacement remote to get you back on the road.

How to Confirm Your FCC ID Is OUC6000066

To avoid returns and headaches, match your FCC ID:

1. Remove your old key fob battery cover.
2. Look at the back of the circuit board or inside the shell.
3. You should see: FCC ID: OUC6000066.

If the FCC ID shows something like KOBGT04A, HYQ, or any code other than OUC6000066, this remote is not compatible.

How to Check Non-Proximity vs Smart Key

You’re non-proximity (this key fob fits) if:

• You physically insert and turn a metal keyin the ignition.
• There is no push-to-start buttonon the dash.
• The car will not start if the key is not in the ignition cylinder.

You have a proximity/smart key (this will not fit) if:

• You have a Start/Stop buttonon the dash.
• The car starts with the fob in your pocket or bag.
• There’s no traditional key turnin the steering column.

When This Cadillac Key Fob Will NOT Work

• Your model has push-to-start / proximityor smart key system.
• Your original remote has a different FCC ID(not OUC6000066).

Keylessbest vs Dealer and Other Aftermarket Cadillac Key Fobs

Price vs Dealer Cadillac Key Fob

Cadillac dealer pricing for an OUC6000066 remote is usually high once you add parts + programming.

Cheap Clone Remotes vs Keylessbest Quality

Not all aftermarket Cadillac OUC6000066 key fobs are equal. Here’s the difference:

Cheap Clone Remote	Keylessbest Cadillac OUC6000066 Fob
Inconsistent 315MHz boards	Stable, tested 315MHz PCB
Thin plastic, weak key ring loop	Thick shell, reinforced loop
Generic low grade buttons	OEM-style buttons with crisp feedback
No real QC or pre-testing	Each remote is tested before it leaves us
Higher failure and return rate	Built for daily US driving conditions

You’re not just buying “a remote”; you’re paying for reliability you don’t have to think about.

Programming Your Cadillac  Key Fob OUC6000066

Common Programming Issues & How To Avoid Them

Avoid headaches by checking these before you go:

• Wrong FCC ID:Make sure your old remote or your research confirms FCC ID OUC6000066. If your old fob shows something else (like HYQ or a different code), this one won’t program.
• Proximity vs nonproximity:If your Cadillac is pushtostart with a smart key, this remote is not for you.
• Weak car battery:A low vehicle battery can cause programming to fail or drop keys from memory.
• Too many keys in memory:Some vehicles have a limit; your locksmith can clear old keys if needed.

If programming fails, 9 out of 10 times it’s wrong remote or vehicle system issues, not the chip itself.

Cutting the Emergency Key Blade

Why You Still Need the Emergency Key (Even With Remote Start)

Even with remote start and keyless entry, the metal emergency key blade on your 2007–2014 Cadillac Chevrolet GMC key fob OUC6000066 still matters. You’ll need it when:

• The key fob battery dies
• The car battery is low or dead
• The remote gets damaged or lost
• You need to manually unlock the door or turn the ignition (non proximity only)

Without a cut emergency key, you’re one dead battery away from being locked out.

Where to Get the Cadillac Emergency Key Blade Cut

For this Cadillac nonproximity key fob (FCC ID OUC6000066, 315MHz), you can get the emergency key blade cut at:

• A local automotive locksmith(usually the best balance of price and skill)
• Some Cadillac or GM dealers (depends on policy)
• Local key shops that advertise laser key cuttingor highsecurity automotive keys

What Locksmiths Need to Cut This Key Correctly

To cut your Cadillac emergency key blade, the locksmith will typically need:

• Your VIN(vehicle identification number)
• A working key(if you still have one) or the original blade as a reference
• Photo IDand proof of ownership (title, registration, or insurance card)

Tell them this is a Cadillac OUC6000066 nonproximity key fob for a CTS, DTS, or SRX so they know it’s a standard highsecurity sidemilled blade.

If the Dealer Refuses to Cut an Aftermarket Key

Some dealers won’t cut aftermarket Cadillac key fobs, even if they’re OEM spec. If that happens:

• Call an independent automotive locksmith– most will cut and program aftermarket keys daily
• Ask the dealer for a key code printout(some will provide it for a small fee) and take it to a locksmith
• Be upfront that it’s an aftermarket Cadillac replacement remote; plenty of U.S. locksmiths are used to this and won’t care

How to Verify the New Blade Works

Before you leave the shop, test the emergency key blade:

• Door test: Manually lock and unlock the driver’s door with the key. Make sure it turns smoothly in both directions with no sticking
• Ignition test (nonproximity only): Insert the key, turn to ON and START. Confirm the key turns fully and starts the engine
• Feel check: The key should slide in and out cleanly, with no grinding or force

If anything feels tight, rough, or inconsistent, have the locksmith recheck the cut right away.

How to Verify the Correct Cadillac Key Fob Before You Buy

Before you order a 2007-2013 Cadillac CTS DTS SRX key fob OUC6000066 from Keylessbest, you want to be sure it’s the exact match. Here’s how I tell customers to double-check fitment so they don’t waste time or money.

Match Your Old Remote’s FCC ID and Buttons

Compare Shell Style and Chip Type

Use Your Owner’s Manual and Door Lock Style

Photo Tips for Compatibility Checks

If you’re not 100% sure, send us clear photos so we can confirm for you before you buy:

• Front and back of your current key fob(close-up, in good light so we can read FCC ID and part numbers).
• The key bladeand ignition cylinder area.
• The driver’s door lockand interior start method (key slot or push button).

Good clear pictures let us verify if our Cadillac 6 buttons 315MHz OUC6000066 remote is the right match, just like we do when helping customers with other OEM-style remotes (for example, our Toyota Prius OEM-style keyless remote uses the same verification process).

Using and Maintaining Your Cadillac OUC6000066 Key Fob

Daily Use Tips to Extend Remote Life

I want your Cadillac OUC6000066 key fob to last years, not months. Here’s what I recommend:

• Use the buttons firmly, not aggressively– no hard jabbing or pressing with keys/nails.
• Don’t pocket it with coins or sharp keysthat can crack the shell or wear the buttons.
• Avoid constant “clicking” just to hear the horn– that kills batteries fast.
• If your car doesn’t respond, move a few feet closer firstbefore assuming the remote is bad.

How to Safely Replace the CR2032 Battery

This Cadillac 6-button remote uses a CR2032 battery. Swap it like this:

1. Open the shell carefullywith a small flat screwdriver or plastic pry tool at the seam.
2. Note battery orientation(which side is facing up) before removing it.
3. Remove the old CR2032, then insert a new name brand CR2032 with the same orientation.
4. Avoid touching the battery contactswith greasy or wet fingers.
5. Snap the shell back together and test Lock/Unlock from a short distance.

Change the battery every 1–2 years or when range noticeably drops.

Cleaning and Caring for the Cadillac Key Fob Shell

Keep the shell clean so the buttons don’t stick and the electronics stay protected:

• Wipe with a soft, slightly damp cloth and mild soap if needed.
• Use a cotton swab around the buttons to clear dirt and pocket lint.
• Never use harsh chemicals, alcohol, or solvents on the plastic or rubber.

“Complete Remote” vs “Shell Only” vs “Refurbished”

Most listings fall into one of three categories:

Complete Remote:

• Brand-new shell
• New internal board + transponder chip
• Ready to program and cut
• This is what we manufacture and sell.

Shell Only:

• Just the outer case and buttons
• No chip, no board – you move your old guts over
• Good only if your current remote works but the case is broken.

Refurbished:

• Used OEM internals cleaned and installed into a new shell
• Usually works fine but not truly new

If you want a full replacement for a lost or dead fob, make sure it clearly says complete remote with electronics and chip.

Smart Questions To Ask Before You Order

Before you hit “buy,” ask the seller:

• Does this key fob use FCC ID OUC6000066 at 315MHz?
• Is this a complete remote, including electronics and chip?
• Can my local locksmith program this remote, or is dealer-only programming required?
• What’s the warrantyif the key fob won’t program or fails early?
