Ford Focus key replacement in Los Angeles

Ford Focus keys by year

What kind of key does your Focus actually use?

The Focus sold in the US from 2000 through the 2018 model year, and the key changed more than most owners expect. The first thing we ask on the phone is the year, because the year tells us the chip family, the blade style and how the car will be programmed. A 2003 Focus and a 2016 Focus are close to different animals when it comes to the key.

There are three eras. The first generation (2000-2007) uses a standard transponder key. The second generation (2008-2011) keeps the same 4D63 chip family that arrived late in the first generation. The third generation (2012-2018) moves to a high-security side-milled blade with an 80-bit 4D63 chip, and on some 2015 and newer push-button trims, a 128-bit smart fob.

Every year in our data is a transponder or flip key with a mechanical backup key, and every year can be handled when all keys are lost. What changes from era to era is how careful we have to be about the chip, and what machine cuts the blade. If you want the wider picture for the brand, our Ford key replacement page covers the other models, and the car keys overview explains how we approach every make.

The year-by-year table on this page lists each model year. The sections below explain what that table means for you in practice.

What do 2000-2004 Focus owners need?

Focus models from 2000 through 2004 use a Texas 4D60 chip in an H74-PT or H86-PT style key blank. This is a detail that trips up a lot of shops. The US Focus is an outlier: it did not use the 4C chip found on many other Fords of the early 2000s. If someone treats it like a Taurus or an Escape, they can end up with a key that fits the lock but never starts the car.

The 4D60 and the 4D63 are not interchangeable. A 4D63 key will not stand in for a 4D60 car, and the reverse is also true. That is why we do not cut anything for these years until we know which chip the car expects.

These cars are now old, and the wear shows in the lock, not just the key. The mechanical side matters as much as the chip. The cut pattern on these keys has eight cuts, and worn blades eventually stop turning the door locks and the ignition. A key that has gone through twenty-plus years of pockets is often rounded off enough that copying it makes a worse copy.

If you have one working key, the usual path is a duplicate cut from it with a new transponder programmed to the car. If you have none, we can still make a key from the vehicle itself. Both routes are possible for every year in this era.

What about the 2005 Focus, where the data is split?

The 2005 model year is a boundary year, and we say so plainly. Blank listings for the 4D60 chip run through 2005, while fitment for the 4D63 chip starts at 2006. Catalogs disagree, and our own data marks 2005 as conflicting rather than verified. We will not tell you over the phone which chip your 2005 uses, because anyone who does is guessing.

What we do instead is read the existing key or the VIN before cutting anything. If you still have a working key, we can identify the chip from it. If every key is lost, the VIN and the car itself tell us what to build. That check costs us very little time and saves you from paying for a key that will not start the engine.

If you own a 2005 Focus, tell us the VIN when you call. It is printed at the base of the windshield on the driver's side and on the driver's door jamb sticker.

What do 2006-2011 Focus owners need?

From 2006 through 2011, the Focus uses the 4D63 chip family, confirmed by Focus fitment listings that run from 2006 into 2011 and 2012. These are 40-bit-era cars. Dual-mode 40/80-bit aftermarket chips cover them, which is useful because it gives us a reliable part for the whole run of years.

The key is still a conventional transponder with a mechanical blade, and the car is programmed through the OBD port. No dealer-only step appears in our data for these years. If you have an original key, we can duplicate it. If you do not, we can make a key from scratch, provided we can verify the vehicle.

These second-generation cars are the ones we see most with a simple complaint: the owner has one key, it is worn, and they want a spare before the only one fails. That is the least expensive moment to act, and it is the moment we recommend.

What changed on the 2012-2018 Focus?

The third generation brings a high-security side-milled HU101 blade, listed as H94, paired with the 80-bit 4D63 chip. This is a much more precise blade than the old eight-cut key. It needs a specialty side-mill machine to duplicate. A hardware-store kiosk cannot do it, and a general key machine without the right cutter will not either.

Flip and non-flip configurations exist, so we confirm the shell style with you. The flip version folds the blade into the fob, and the hinge is the part that tends to fail.

Then there is the push-button question. On 2015 and newer Focus models, Titanium and ST push-button trims use a 128-bit Hitag Pro smart fob, listed as KR5876268 and confirmed for 2015-2019. US Focus sales ended with the 2018 model year, so the later listing is a catalog range, not a car you will find in a showroom. Bladed trims in those same years keep the 80-bit 4D63 on the HU101 blade.

So a 2016 Focus might have either setup, depending on trim. The year-by-year table treats the bladed key as the baseline, and the push-button trims are the exception. If your car starts with a button and no key in the ignition, you have the smart fob version. We will confirm the exact setup by VIN or in person before ordering anything, and we will tell you if anything about the programming turns out different from what the data suggests.

Duplicate or all keys lost: what is the difference?

Every Focus year in our data needs the original key for a straightforward duplicate, and every year allows an all-keys-lost job. The two jobs are not the same amount of work.

A duplicate means you hand us a working key. We cut a new blade, match the chip and program it to the car. That is the lighter-cost route, and it is usually the more economical way to get a spare.

All keys lost means there is nothing to copy. We work from the vehicle, usually the VIN and the lock itself, to cut a blade that matches and then program a new key to the car's immobilizer. It takes more steps and more equipment, and it is where a mobile van earns its keep, because your Focus may not be drivable to a shop.

Here is what that means by era:

• 2000-2004: duplicate from a working key, or all keys lost with a new 4D60 key built from the vehicle.
• 2005: either path starts with reading the key or the VIN, because the chip is not settled in the catalogs.
• 2006-2011: duplicate or all keys lost, both with the 4D63 family.
• 2012-2018 bladed trims: duplicate or all keys lost, with the side-milled HU101 blade cut on a specialty machine.
• 2015-2018 push-button trims: we confirm by VIN before we promise a route, since the smart fob is a different part.

How is a Focus key programmed, and is the dealer required?

Our data shows OBD programming for every Focus year, with no special secure-access registration required. In plain terms: a technician connects to the diagnostic port under the dash, tells the car's anti-theft system (Ford calls it PATS) that a new key is allowed, and then tests it. No year in our data requires you to go to the dealer.

We want to be honest about the limits, though. Our data covers the chip and the general method. It does not replace checking the actual car. The 2005 boundary year is marked conflicting, and the push-button smart fob trims are the ones we confirm in person. If a particular Focus turns out to need something we cannot do at the curb, we will say so before you pay for anything, instead of discovering it halfway through.

The usual sequence looks like this:

1. You call (213) 577-1366 and give us the year, trim and whether the car has a push button or a key slot.
2. We confirm the chip and blade from the key you still have or from the VIN.
3. We cut the blade, on the side-mill machine if it is an HU101.
4. We connect to the OBD port and program the new key, and any remaining keys you want to keep.
5. We test the lock, the ignition and the start before we leave or hand it over.

What affects the price of a Focus key?

We do not quote numbers on a web page, because the same Focus can lead to very different jobs. These are the real factors:

• Which era the car is: an eight-cut 4D60 key is a simpler part than a side-milled blade or a smart fob.
• Duplicate versus all keys lost: working from a key you hand us takes less time than building from the vehicle.
• Key style: a plain transponder is the lighter-cost choice, a flip key costs more to build, and a smart fob generally costs the most.
• How many keys you want programmed: adding a spare during the same visit is usually more economical than a second trip.
• Where the car is: a Focus at our Westwood storefront is a different job from a van visit to a car that cannot be moved.
• Condition of the lock: worn ignition wafers or a damaged lock can add repair work to a key job.

What commonly goes wrong with Focus keys?

The problems below come from our Focus data, and they sort by era.

• Worn ignition lock wafers on high-mileage cars: the key sticks or will not turn. This shows up on 2000-2011 cars.
• Worn eight-cut blades that stop turning the locks, also on the older cars.
• The PATS theft light flashing: the engine cranks but will not start because the chip is not being read. This appears in every era.
• Hardware-store copies cut without a transponder: they open the doors but will not start the engine. This is the classic trap on 2000-2011 cars.
• Broken flip-key hinges and worn shells on 2012-2018 bladed keys.
• Fob battery failure on the flip and smart fob keys.
• High-security side-milled blades that no ordinary key machine can copy.

When should you call us, and when should you call the dealer?

Call us when you are stranded, when you have lost your only key, or when you want a spare without a dealership appointment. We have been in business since 1987, with a storefront at 10740 Wilshire Blvd in Los Angeles, 90024, plus mobile vans, and we serve 140 cities across Los Angeles and Ventura counties. It is one company, not a dispatch service passing your call along, and David oversees the work.

The dealer makes sense in a narrow set of situations: a warranty or recall question, or a repair of the car's electronics that goes beyond the key. For a plain replacement or spare, a locksmith is usually the more economical route and often the quicker one, because we can come to the car.

Whoever you hire, ask for their California BSIS locksmith company (LCO) license number. California requires locksmith companies to hold one, and a legitimate company will give it to you without hesitation.

To start, call (213) 577-1366, which is answered 24 hours a day, every day. You can also use our contact page, or go back to our home page for the full list of services.
