Lockheed Martin MyTimecard Access Guide (2026): Secure Login, Timekeeping Rules, And Enterprise Troubleshooting

Lockheed Martin MyTimecard is the centralized, defense-grade timekeeping web platform used by Lockheed Martin employees, sub-contractors, and authorized personnel to record labor hours, manage charge codes, and ensure strict compliance with federal defense contract regulations.

Because Lockheed Martin operates under stringent Department of Defense (DoD) oversight, accessing MyTimecard requires passing multi-factor authentication (MFA) protocols through LMSecure, Exostar, or corporate-issued hardware tokens. This guide provides an operational walkthrough for accessing MyTimecard in 2026, entering labor hours accurately, adhering to Defense Contract Audit Agency (DCAA) standards, and resolving critical network access errors.

Navigating the MyTimecard Portal Ecosystem and Access Pathways

Accessing MyTimecard depends on your employment classification (full-time employee, direct subcontractor, or external vendor) and your physical connection to the Lockheed Martin enterprise network (Intranet vs. Extranet/Internet).

Note: Ensure you are accessing official enterprise portals. Lockheed Martin never requests credentials over unencrypted channels or non-corporate websites.

1. On-Network Access (LM Enterprise Network / VPN)

When connected directly to the Lockheed Martin internal network via a hardwired corporate workstation or encrypted Virtual Private Network (VPN), accessing MyTimecard is streamlined through Single Sign-On (SSO):

• Launch an enterprise-approved browser (Microsoft Edge or Chrome configured with corporate security profiles).
• Navigate to the internal employee intranet portal (LMPeople or the direct internal MyTimecard URL).
• Authenticate using your Lockheed Martin Windows NT credentials or Personal Identity Verification (PIV) / Smart Card.

2. Off-Network Access (External Portal & Exostar Authentication)

For remote employees, traveling staff, and external contractors accessing MyTimecard outside the internal firewall:

• Navigate to the official Lockheed Martin External Access Portal (access.lockheedmartin.com or via Exostar Secure Access Manager).
• Select your assigned authentication method: Exostar Hardware Token, Mobile Pass OTP (One-Time Password), or FIDO2 Security Key.
• Enter your User ID, PIN, and dynamically generated token code to complete the LMSecure handoff to the MyTimecard web application.

Defense Contract Compliance & DCAA Timekeeping Rules

Time tracking at Lockheed Martin is not merely an internal administrative task; it is a legally binding reporting requirement subject to regular audits by the Defense Contract Audit Agency (DCAA). Failure to record hours accurately can lead to severe regulatory penalties, contractual disputes, or internal disciplinary actions.

Daily Recording RequirementEmployees and contractors must record all worked hours daily. Waiting until the end of the pay period or weekly billing cycle to populate labor hours violates DCAA compliance standards and internal enterprise procedures.

Core Timekeeping Imperatives for 2026

• Real-Time Labor Allocations: Hours must be charged directly to the specific Charge Number / Work Breakdown Structure (WBS) element corresponding to the actual work performed. Charging hours to an unassigned or incorrect program code is strictly prohibited.
• Total Time Reporting: All hours worked must be logged, including uncompensated overtime for salaried exempt personnel, to ensure accurate cost accounting standards (CAS) calculations.
• Immediate Correction Logs: If an edit is made to a previously submitted timecard, MyTimecard prompts the user to input a mandatory "Reason for Change." This audit trail is permanently logged and accessible by DCAA auditors.
• Pre-Authorization for Overtime: Non-exempt personnel and sub-contractors must receive explicit supervisor authorization prior to recording overtime hours in MyTimecard.

Step-by-Step Guide: Submitting Hours in MyTimecard

To ensure seamless payroll processing and contract labor billing, follow this standardized operational workflow for logging daily hours within the MyTimecard system.

1. Log In to the MyTimecard Portal: Access the application through LMPeople or the remote Exostar gateway using your multi-factor authentication credentials.
2. Select the Active Pay Period: Confirm that the correct week ending date is selected on your active timecard grid.
3. Verify Charge Numbers: Cross-reference your assigned program WBS or task charge codes with your project lead. If a required charge code is missing, use the "Add Charge Code" lookup tool within the system.
4. Input Daily Labor Hours: Enter total hours worked per day against each assigned charge line. Ensure hours are broken down accurately by project task if working across multiple defense contracts.
5. Review System Alerts: The MyTimecard system automatically runs validation checks. Address any flagged discrepancies, such as unauthorized holiday entry, missing shift differentials, or total hour mismatches.
6. Sign and Submit: At the conclusion of the work period (typically Friday end-of-shift), click the "Sign/Submit" button. Entering your electronic signature legally certifies that the reported hours reflect actual time worked.

2026 MyTimecard Access Methods & System Requirements

The table below outlines the system specifications, access pathways, and authentication protocols required to connect to Lockheed Martin MyTimecard in 2026.

Troubleshooting Common MyTimecard Access and Technical Errors

System lockouts, authentication loops, and invalid charge codes can prevent timely timecard submission. Use the diagnostic matrix below to resolve common operational issues.

1. Exostar / LMSecure Authentication Failure

• Symptom: The system rejects your login credentials or displays an "Invalid Token / Synchronisation Error."
• Resolution: Ensure your Exostar hardware token or Mobile Pass app time drift is synchronized. If using a physical token, re-enter your PIN followed immediately by the 6-digit passcode without spaces. If the issue persists, perform a credential resync through the Exostar Self-Service portal.

2. Missing or Inactive Charge Codes

• Symptom: The required WBS charge code does not appear in your default MyTimecard dropdown menu.
• Resolution: Charge codes expire or lock automatically upon project milestone completions. Request your work package manager or business area administrator to add your employee ID to the charge code's Authorized Charging List (ACL) in the enterprise ERP platform (SAP/LMPeople).

3. Timecard Locked / Read-Only Status

• Symptom: The timecard grid is grayed out and prevents data entry.
• Resolution: A timecard becomes locked once the supervisor has initiated the approval cycle or when payroll processing has begun. Contact your functional manager or timekeeper to formally "un-approve" or reject the timecard back to draft status so edits can be applied.

4. Browser Clearing and Cache Artifacts

• Symptom: Continuous redirect loops back to the login page or blank white screens upon selecting MyTimecard.
• Resolution: Clear your browser's SSL state, cookies, and local cache. Ensure third-party cookie blocking is disabled for *.lockheedmartin.com and *.exostar.com domains.

Operational Comparison: Enterprise Timekeeping vs. Standard Corporate Portals

Defense contractors operate under different regulatory standards compared to commercial enterprises. Understanding these differences highlights why MyTimecard enforces strict data entry controls.

Defense-Grade Timekeeping (MyTimecard)

• Regulatory Standard: DCAA / FAR (Federal Acquisition Regulation) Compliance.
• Audit Trail Requirements: Strict, permanent change-log tracking requiring explicit reason entries for any post-submission edits.
• Charge Code Granularity: Hour tracking tied directly to government contract WBS numbers down to 0.1 hour increments.
• Authentication Security: Mandated Hardware MFA, Smart Cards, or Exostar Secure Access Manager.

Standard Commercial Time Tracking

• Regulatory Standard: FLSA (Fair Labor Standards Act) basic compliance.
• Audit Trail Requirements: Basic supervisor approval overrides without mandated federal audit logs.
• Charge Code Granularity: General departmental billing or simple project categories.
• Authentication Security: Standard single-factor or basic email/SMS multi-factor authentication.

Frequently Asked Questions (FAQ)

How do I log into Lockheed Martin MyTimecard from home?

To log in from home, access the external LMSecure access portal (access.lockheedmartin.com) or the Exostar gateway using an approved web browser. You must authenticate using your enterprise User ID, PIN, and hardware token or Mobile Pass OTP.

What should I do if I forget to submit my MyTimecard on time?

If you miss the submission deadline, contact your immediate supervisor and departmental timekeeper immediately. They can unlock the timecard or issue a manual override ticket through the IT Service Desk to allow retro-active entry while preserving DCAA audit logging.

Why does MyTimecard require a reason code when changing hours?

Federal defense regulations require a complete, unalterable audit trail for all labor adjustments on government contracts. Entering a reason code justifies why an entry was modified after the initial work date, preventing fraudulent billing practices.

Can sub-contractors use the standard internal MyTimecard portal?

Sub-contractors generally do not have direct internal intranet access and must log hours via the external Exostar portal or an approved vendor management interface, depending on their specific contract terms with Lockheed Martin procurement.

What is the official Lockheed Martin IT Help Desk contact method for timecard issues?

If technical troubleshooting steps fail, contact the Lockheed Martin Enterprise Service Desk (ESD) via the internal help portal or by phone at the designated regional support lines (e.g., 1-800-435-7700 for US-based operations).

Enterprise Best Practices for Effortless Compliance

Maintaining uninterrupted access to MyTimecard requires proactive management of your enterprise credentials. Always renew your Exostar digital certificates prior to expiration, regularly check that your assigned WBS charge codes are active before starting project work, and strictly adhere to daily logging schedules. By maintaining daily timekeeping discipline, employees and contractors ensure contract compliance, accurate payroll execution, and seamless DCAA auditing throughout 2026.
