Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how

What stands out
Owners have filed 37 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA electrical complaint has been filed on this vehicle in over 12 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Power door locks fail intermittently across all four doors on 2010 Focus models, trapping occupants inside or preventing entry. Owners describe doors that won't unlock via key fob, interior switches, manual handles, or key insertion—sometimes for extended periods. Many report the malfunction stops when brought to the dealership, making diagnosis difficult. When fixed, the problem recurs. Ford dealers replace door actuators, latches, linkages, and latch assemblies, sometimes multiple times per vehicle, indicating a systemic design issue rather than isolated component failure. One owner documented replacing the same door handle three times due to a breaking plastic latch piece inside. Temperature and moisture correlation appears inconsistent—some failures happen in hot weather, others random. Dealerships acknowledge seeing the problem repeatedly but claim lack of diagnostic capability or blame owners.
Ignition and starting problems occur with similar unpredictability: keys require excessive force, multiple turns, wiggling, or steering-wheel manipulation to start the engine. Some owners report the instrument cluster or ignition switch fails to recognize the key's security chip, necessitating ignition replacement. One new car stalled seven times in 23 days due to instrument cluster issues causing the engine management to reject the coded key.
Door ajar warning switches malfunction, falsely signaling open doors and causing interior lights to stay on while driving, preventing automatic door locking and forcing doors to unlock when manually locked.
Unrelated electrical issues include tail lights failing, battery drain, and alarm/trunk spontaneous activation.

Failure modes owners describe
Power door lock actuator/latch failure (all doors, intermittent)
Door locks fail to respond to key fob, interior unlock switches, manual handles, or key insertion. All four doors affected individually or collectively. Failure is intermittent and may resolve temporarily; when door opens at dealership, technician cannot diagnose root cause. Recurs after parts replacement.
When: Occurs from early ownership (within months) to 200,000 miles; some reports at 16 miles, others at 100,000+ miles
Symptoms owners cite: Door will not unlock via key fob; Door will not unlock via interior door lock button; Door will not open when handle pulled from inside or outside; Doors lock in locked position and cannot be unlocked; Occupants trapped inside vehicle; Intermittent behavior—works sometimes, fails other times; Multiple doors fail simultaneously or sequentially; Malfunction stops when vehicle is brought to dealership
Repairs/costs cited: Ford dealers replace door actuators, latches, linkages, and latch assemblies. One owner reported replacing the same door handle three times. Parts cost ranges mentioned: ~$400–$1,200 for diagnosis and repair. Repairs are temporary; failures recur.
Recalls/TSBs owners mention: Ford has redesigned door latch mechanism (requiring replacement of door latch, door ajar switch, rods, and plates instead of single component). Dealerships acknowledge frequent reports of this problem. No recall issued as of complaint dates. Warranty extensions denied by Ford Motor Company.
Ignition switch/key recognition failure
Key does not turn properly in ignition cylinder, requires excessive force or multiple attempts, or steering wheel manipulation to initiate start. Instrument cluster fails to recognize security chip in key, causing engine to refuse start or to stall immediately. Engine shuts off at speed without warning.
When: From 174 miles on new car to 100,000+ miles; degradation often occurs over months
Symptoms owners cite: Key will not turn ignition or turns only partway; Key requires excessive force or multiple tries to turn; Engine stalls while driving at highway speed or in intersection; Stalling occurs 7 times in 23 days on new car; Car will not start after stalling for extended period; Steering wheel must be turned or gear shifted to enable start; Key must be wiggled multiple times to achieve ignition connection; Instrument cluster displays coded-key rejection error (per dealer diagnosis)
Repairs/costs cited: Dealers report replacing ignition switch and reprogramming key. One owner cited $400 repair cost plus towing. Another owner reported ignition and key reprogramming expense. Dealer service notes indicate forced computer loading required for new instrument cluster; manufacturer stated 'never seen this before in a new car.'
Recalls/TSBs owners mention: Dealer service worked with manufacturer on programming new computer on one case but stated they were unsure of root cause. No TSB or recall mentioned. Warranty does not cover post-warranty ignition failures.
Door ajar warning switch malfunction
Door ajar switch falsely signals that driver's door is open when it is properly closed. Dashboard display locks, interior dome and map lights remain on while driving, and automatic door locking function is disabled. Doors unlock immediately after being manually locked.
When: Occurs at 36,000 miles and higher; one report at 42,000 miles
Symptoms owners cite: Dashboard falsely displays door ajar warning; Interior lights stay on continuously while driving; Odometer/mileage display becomes inaccessible; Automatic door locking does not function when car starts moving; Manually locked doors immediately unlock; Door ajar alarm will not turn off until engine starts; Hazardous night driving due to interior lighting
Repairs/costs cited: Ford redesigned mechanism requiring replacement of door latch, door ajar switch, rods, and plates instead of single switch. One owner cited $182 parts cost plus ~$150 labor. Dealers acknowledge repeated reports of this problem.
Recalls/TSBs owners mention: Ford has redesigned door latch assembly but has not issued recall or TSB. Warranty denied beyond 36,000 miles; owners responsible for diagnosis and repair costs.
Engine stall at speed (loss of throttle/power)
Engine loses power or shuts off completely while driving at highway speeds, city speeds, or during turns. Vehicle slows randomly or stops without warning. Check engine and wrench warning lights illuminate. Problem is unrelated to ignition switch failures (distinct from those complaints).
When: Occurs within 300 miles on new car and recurs; also at 87,000 miles on used car
Symptoms owners cite: Engine loses all power or throttle without warning; Vehicle stalls while driving at 65+ mph on highway; Vehicle stalls while driving 40 mph on busy street; Vehicle stalls during turn in intersection; Vehicle hesitates on acceleration; Check engine light illuminates; Wrench warning light illuminates; Stalling occurs on multiple occasions in short timeframe
Codes mentioned: Check engine light, Wrench warning light
Repairs/costs cited: One independent mechanic diagnosed throttle body sensor replacement needed. Owners cite $600 repair cost. Not covered under powertrain warranty per owner complaint.
Recalls/TSBs owners mention: No recall or TSB mentioned. Owners report forum discussions indicating widespread occurrence on Focus models but no manufacturer action documented.
Tail light/headlight electrical failure
Tail lights and/or headlights fail or malfunction. One owner reported tail light cover arcing/shorting when tapped and bulb burning black. Tail light inoperative despite control switch in off position; headlights only function when control turned to on position.
When: Within 5-year ownership period; requires multiple bulb replacements within ownership
Symptoms owners cite: Tail light fails to illuminate; Brake light inoperative; Blinker light inoperative or blinks abnormally fast; Headlight will not turn on with automatic setting; Tail light cover/lens arcs when tapped; Bulb filament burns black prematurely
Repairs/costs cited: Bulb replacement attempted; recurs on same side multiple times within ownership period
Alarm and trunk spontaneous activation
Car alarm sounds at random intervals without triggering event. Trunk pops open without button activation.
When: Timing and mileage not specified in complaint
Symptoms owners cite: Alarm activates at various times without user input; Trunk opens spontaneously without button press
Engine continues running after key removal from ignition
Engine does not shut off when key is turned and removed from ignition cylinder.
When: Mileage and frequency not specified
Symptoms owners cite: Engine continues to run after key turned and removed from ignition

What owners are reporting 2 most recent
It had trouble starting. We thought to believe it was the battery, but knowing I changed the battery within the last year, skeptical. Now it won't start at all. My mechanic says it has to do with either the switch, cylinder or whole assembly. *tr
The dashboard display incorrectly states that the drivers door is open when it isn't. This causes the dashboard display to "lock" and I can no longer see the odometer or the mileage. Furthermore the interior lights continuously stay on even when traveling down the road (this results in a safety issue as the interior lights make it difficult to see the road at night). Also, the incorrect open…
