Ford Focus & Fiesta Ignition Repair in Plano
Ignition repair for the Ford Focus and Fiesta in Plano — worn lock cylinders, keys that will not turn or come out, PATS antenna faults, ignition switch failure, and repair cost versus replacement.
These are high-mileage cars. A Focus or a Fiesta that has spent eight years commuting on the Dallas North Tollway has turned its ignition something like six thousand times, and lock cylinders are mechanical parts with a finite number of cycles in them. The failure is almost always gradual: a little play in the key, then a wiggle, then a specific angle of the steering wheel that makes it work, then one morning nothing. Caught early it is a rebuild. Caught late it is a replacement plus a key. For mobile Ford ignition service in Plano, call or text (945) 307-3827.
Quick Answer
As of August 2026, Ford Focus and Fiesta ignition repair in Plano runs roughly $170 to $340 to rebuild a worn lock cylinder keyed to your existing key, and $250 to $450 to replace the cylinder with a new key cut to match. Most jobs are completed on-site in forty-five to ninety minutes. Electrical faults — a PATS antenna or an ignition switch behind the cylinder — are a different repair at a different price, which is why the diagnosis comes before the parts.

Three Different Parts, Three Different Failures
The word "ignition" covers three components that fail independently, and telling them apart is most of the job.
The lock cylinder is the mechanical part your key goes into. It contains brass wafers that read the cuts on the blade and allow rotation. Wear here produces mechanical symptoms: the key will not go in fully, will not turn, turns only from a specific steering wheel position, or goes in and will not come back out.
The PATS transceiver ring is the coil wrapped around the cylinder that reads the transponder chip in your key head. It is electronic and it fails independently of the cylinder. Symptoms are the opposite of mechanical: the key turns perfectly, the engine cranks and immediately dies or does not crank at all, and the theft indicator on the dash flashes.
The electrical ignition switch sits behind the cylinder and is what actually sends power to the accessory, run, and start circuits. When it fails you get dead accessories in one position, or a car that cranks but has no dash lights, or intermittent power loss while driving — which is the version worth taking seriously immediately.
A shop that replaces the cylinder on a PATS fault has sold you a part that changes nothing. Our cross-make triage for this lives under ignition repair in Plano.
Focus Specifics
2012-2018 Focus
The third-generation Focus is the most common ignition job we see on this nameplate in Plano. High volume, high mileage, conventional bladed key with a PATS chip. Cylinder wear is the dominant failure. In most cases the cylinder can be rebuilt with fresh wafers and keyed to your existing key, which means you keep carrying the same key and do not end up with a second one for the same car.
A specific symptom worth flagging: a Focus where the key will not come out of the run position. That is usually a worn cylinder or a failed lock actuator rather than a transmission interlock fault, though on automatics the interlock is worth ruling out first — put the car firmly in park and try again before assuming the worst.
2019-onward and ST / RS trims
Later cars and higher trims may use keyless entry with push-button start, which removes the cylinder from the equation entirely and shifts any fault to the start switch, the steering lock actuator, or proximity detection. Performance trims share immobilizer architecture with the standard car — there is no reason an ST should be quoted higher for the same repair.
Fiesta Specifics
2011-2019 Fiesta
Small car, conventional bladed key, same PATS architecture as the Focus of the same era. Cylinders wear the same way. What is slightly different is packaging: column trim on the Fiesta is tight, which adds a few minutes to disassembly but does not change whether the job is mobile.
Fiesta owners report the broken-key-in-cylinder scenario more often than average, and the reason is usually the key itself. These cars are frequently on their original key after a decade, and a blade with rounded, worn cuts snaps more easily than a fresh one. Extraction is a fast job on its own — under half an hour — and it does not require replacing the cylinder if the cylinder survived.
The Key Is Half the Problem
This is the part most articles skip, and it is where owners lose the most money.
A worn key wears the cylinder faster than anything else. Every time you insert a blade whose cuts have rounded off, it drags across the wafers at slightly the wrong depth. Over years the cylinder wears to match the worn key. At that point two bad things are true: the cylinder is out of spec, and a fresh key cut to factory dimensions may not work in it at all.
So the practical advice: if you are having a cylinder repaired and your key is visibly rounded at the tip or the cuts have lost their edges, replace the key at the same time. Repairing the cylinder and putting the same worn key back into it is a two-year fix. If you need the key side handled separately, our Ford PATS key replacement guide covers cost and process.
The other half of prevention costs nothing: take the weight off your keyring. A heavy ring hanging from a bladed Focus or Fiesta ignition is a lever applying constant downward force every time you hit a rough patch of road. It is the single largest avoidable cause of premature cylinder wear, and it is free to fix.
When It Is Not the Ignition at All
Two scenarios masquerade as ignition failure and are worth ruling out before a service call.
A weak 12-volt battery. Low system voltage produces symptoms that look exactly like a switch fault — dash lights that behave oddly, a starter that clicks, intermittent no-crank. This is free to check and it is the cause more often than owners expect.
A module-level fault. If the diagnosis points past the switch and the cylinder into a control module that has failed or been replaced without being written to the vehicle identity, that is a different repair path with a different price. What that work involves is described under PCM replacement and VIN programming. A technician should tell you when you have crossed into that territory rather than working toward it hourly.
What Gets Done On-Site
Cylinder work is genuinely mobile on both cars. The technician removes the column shrouds, extracts the cylinder, and either rebuilds it with new wafers keyed to your existing key or fits a replacement and cuts a key to match. PATS ring replacement is also on-site, though it takes longer and occasionally needs a part sourced, which can push it to a second visit.
Electrical switch replacement varies with how much of the column has to come apart. On a Focus or Fiesta it is usually a same-visit job.
After any cylinder work, the immobilizer is verified — because the PATS ring sits around the cylinder, cylinder work touches immobilizer hardware, and a job is not finished until the car starts reliably from cold.

Frequently Asked Questions
How much does Ford Focus or Fiesta ignition repair cost in Plano?
As of August 2026, roughly $170 to $340 to rebuild a worn cylinder keyed to your existing key, $250 to $450 to replace the cylinder with a new key cut to match, and $200 to $400 for electrical ignition switch replacement.
My key will not turn in my Focus. Is it the key or the cylinder?
Test with a spare key first. If the spare turns cleanly, your original key is worn and the cylinder may still be serviceable. If neither key turns, the cylinder is the likely fault. Also check that the steering lock is not loaded — rock the wheel gently while turning the key.
The theft light flashes and the engine dies right after starting. Is that the ignition?
That is a PATS rejection, not a mechanical ignition fault. Either the key transponder is not being read or the transceiver ring around the cylinder has failed. Replacing the lock cylinder will not fix it.
Can Ford ignition repair be done at my house?
Yes for most jobs. Cylinder rebuild, cylinder replacement, broken key extraction, PATS ring work, and most switch replacement are all mobile on these cars.
Do I need a new key after cylinder replacement?
Not always. In many cases the replacement cylinder can be keyed to your existing key so you keep one key. If your existing key is badly worn, replacing it at the same time is strongly recommended regardless.
My key will not come out of the ignition. What causes that?
Usually a worn cylinder or a failed lock actuator. On automatics, first confirm the car is firmly in park — the interlock will hold the key if the shifter is not fully seated.
